2. Obsolescence

The most common of the five issues are obsolete displays. The display suppliers have discontinued the display without providing a suitable replacement but our customers are still producing their end product.

Why Does This Issue Happen?

For the occurrence of the above issue there are two reasons which are following:

Two Reasons:

1) The overall volumes for this part reached a low threshold, and the supplier does not want to support it.

2) The components within the LCD have gone obsolete or over-dated.

What Can We Do?

Because we create custom displays, we have the ability to be able to produce un-obsolete displays.

1) If volumes are too low to support a custom display, we would recommend changing the end product to accommodate an available standard display. 

2) Solving an obsolescent component is more complicated. We have complete control of all parts within a display, except for the LCD driver IC and the color TFT LCD glass (monochrome glass is not an issue).  

Our process is to find the closest standard TFT panel and closest standard driver (if outdated). 

We do an obsolesce analysis on these replacement components to ensure we have the most extended lifetime with this new arrangement before starting the design work. We use our crossmatch program to redesign the display near these non-obsolete components.

Our focus is on eliminating any differences between the obsolete display and our new replacement. Not only is this process for new customers, but it’s the standard operating procedure for our current clients. We do not have obsolete configurations due to low volumes. We automatically go through the redesign process at no cost to our clients if any component goes obsolete within our display. Therefore, we come to our clients with the obsolescence notification and the solution to keep them up and running. 

Obsolescence

3. Delivery

Why Does This Issue Happen?

If we talk about delivery, longer than expected lead times and inconsistent deliveries lead to missed customer commitments and cause stress on manufacturing.

One of the main reasons customers are forced to switch suppliers is delivery. Learn what goes into actually getting a product to you and how CreateXdisplay might be different.

Missed deliveries are a killer with even if one component is missing, an assembly line goes down, missing revenue goals, affecting operations, and failing customers. Parts frequently have lengthy and variable lead times, leading to production and subsequent delivery problems if they’re not managed effectively.

What Is The Solution?

Proactively address this challenge within your company and the LCD display provider. Assure suppliers’ lead times are accurate in your MRP, Internally. Further, maintain a 2-4-week buffer stock or more depending on component scarcity and lead times.

The LCD display supplier can carry a buffer stock for your application. Effective display providers like CreateXdisplay can adjust production schedules, pressurize the upstream supply chain, partial ship quantities, and accelerate shipments. A good thing is applying these solutions reduces most delivery problems and handles unplanned customer demand. Because we have full production lines. From glass cleaning to final LCD.

Delivery

4. Quality

Quality should not be mistaken with performance as they both are different. This is where the LCD is not meeting the specification standards or simply a clients’ expectations.

Why Does This Problem Occur?

A manufacturing LCD failure is an expensive issue and even it could be more costly later.

Generally, quality issues arise in a few ways. 

First, the LCD’s failure to fulfill the performance specification as intended. This involves customers’ needs and defining what’s required to satisfy the product’s intent.

Second, there are the mechanical and visual aspects of LCD display manufacturing. This includes maximum defect limitations and meeting dimensional tolerances.

What Is The Solution?

A supplier that manufactures to your specific needs will minimize quality issues due to their expertise by modifying the LCD display for your particular product, ability to bring flexibility, and then actively supporting ongoing product improvements.

Quality

5. Performance

What Are the Performance Issues?

This is where the component does not work as you want or expect. The display could meet the specification very well. A little improvement to contrast, sunlight readability, response time, brightness, color gamut could make the end product work better and ultimately help our clients sell more of their product. 

Defining performance begins with the application and some basic questions listed below. 

  • Who is the end-user, and how will they interact with the LCD display? 
  • In what environment will it be used? 
  • How is it being sold to customers? 
  • What type of data does the LCD need to convey? 
  • Is it must be readable by the visually impaired?

What is the Solution?

We can define the ideal display type, pixel density, size, contrast, brightness, temperature range, color gamut response time, etc when performance is fully understood. 

Over-specifying any of these factors will add unnecessary cost, while under-specifying any factor will detract from the end product’s usability. Ensure performance is optimized for your application to be successful. It is critical to find an LCD display provider who will willing to adjust explain them to you in terms of the end-user experience and customize these particular variables.

Performance

6. Cost

What Is The Cost Issue?

Surprisingly cost issue is the least common. The pain of changing LCD suppliers is high, such that all the problems mentioned above end up costing more than a regular cost delta between competitive suppliers.

An LCD’s cost is an obvious challenge as it’s usually the most expensive component. The challenge is that cost is also difficult to quantify and properly understand. Determining the right price to pay depends on three main factors. 

  • What does the display need to do? 
  • What does the display not need to do?
  • What quantity is required? 

The ideal option in most cases is a custom or semi-custom display designed for its application. This is often the most cost-effective solution, despite what many think.

What Is The Solution?

You expect a lower price point with greater volume, which goes hand in hand with provider selection. 

Oversimplifying this for you, imagine three categories; 

  • low-volume – standard product distributors; 
  • mid-volume – built-to-order custom semi-custom suppliers; 
  • high-volume – consumer market suppliers.

You will never get to the optimal volume pricing with a low-volume stocking distributor for a high-volume consumer product. Start work with the right provider who serves that particular category after identifying where you fit.

System-level manufacturability is another cost challenge where display integration improvements can reduce product complexity, improve manufacturing time, and reduce system-level manufacturing defects. For the most seamless LCD integration, additional components such as buttons, LEDs, PCB boards, and connectors are more efficiently integrated on display than a separately assembled component. Clearly, in this case, the LCD cost will go up, but when done right, the system-level cost is reduced to result in a net gain.

Lastly, you need to know system-level costs. You are trading market share and profitability for display savings, and the net result may be decreased profit if you are giving up customer valued performance or functions. The opposite also holds; adding performance that is not necessary (these are attributes that the customer does not value) adds additional product costs.

Are you looking forward to getting a high-quality, advanced and affordable LCD display but do not know what makes it high quality?

Today we will discuss some essential things that you need to know like quality vs. performance factors, developing a well-defined quality assurance process, and quality-related aspects that would be important when buying an LCD display.

A high-quality and affordable LCD display is necessary for fully managing end-user cases. Liquid crystal displays with defects and cosmetic deficiencies can only spoil your reputation with your buyers. However, people are often confused with the terms “performance”  and “quality,” which can lead to incorrect questions in their purchase decisions.

This article will explore the difference between these two terms and answer the question, What makes a high-quality and affordable LCD display?

1. The Difference in b/w Quality And Performance

In this part, we will talk about both performance and quality. 

Performance is an area of quality-focused display elements that the customer would want to see and interact with. 

Quality is about the manufacturer’s proficiency to meet agreed-to-all specifications and requirements. It’s about defining what the product is supposed to do, then producing the product to do that perfectly and consistently.

 

The-difference-in-B/W-quality-and-performance

Additionally, the quality typically contains three main areas:

1.1 Cosmetic

Cosmetic includes some items such as spots, missing pixels, scratches, LCD glass colors, pixel, backlight color, and other prominent or physical defects on the surface. There could also be wrongly assembled components or poorly fused joints on a craft level. 

LCD-cosmetic

1.2 Electrical 

Electrical Is the product operating at the correct voltage? Is the LCD over-driven or under-driven? Is it drawing the right amount of power?

1.3 Performance

Operating temperature, response time, reliability, LED lifetime, contrast, brightness, color gamut, and viewing angle are Example aspects of performance.

Customers may have their unique requirements involving drop-test criteria, specific mechanical limitations, and electrostatic discharge (ESD) beyond these areas.

2. Developing a Well-Defined Quality Assurance Procedure

Designing a high-quality LCD display means that all quality requirements are fulfilled. To get this quality, the manufacturer needs to have a well-defined quality assurance (QA to accomplish this) process. It’s how to consistently meet all the quality requirements.

Developing-a-well-defined-quality-assurance-procedure

Here are the specific QA process areas you should know:

2.1 Qualification 

Qualification is the initial testing of the new product for every performance factor, including contrast, vibration, and temperature cycle.

2.2 Sampling

It is very important to test a predetermined selection of displays to ensure consistency. This may be completely random, including every lot, some other sampling method depending on the sampling plan. In addition, the factors tested for the samples of the product could include every requirement or only a select few.

Sampling-of-LCD

 2.3 Final Assembly Test 

What is being tested after the display is fully assembled? 

  • Functionality,
  • cosmetic defects, 
  • voltage, 
  • all of the above areas? 

All the above factors are often determined by the product, as some require more strict testing than others.

2.4 Process 

What is the documentation, training, tools to ensure that each step of the manufacturing process is as simple and as consistent as possible? And what other processes are put in place to ensure that each display produced consistently meets the original design specification?

There could also be testing throughout the manufacturing process. For example, at PDI, we test 300%—including tests along the manufacturing path to catch any defects early on and avoid adding value to wrong parts, as well as burn-in tests that entail running displays for a certain amount of time at higher temperatures to catch any latent defects.

3. What Are Quality-Related Aspects to Consider When Buying an LCD Display?

From a customer perspective, there are several questions you need to ask your manufacturer before purchasing LCD displays from them:

1) What is the expected defect rate for the type of your desired display?

2) What is the test process of manufacturers? 

For example, 

  • What is tested? 
  • How are they tested? 
  • And how often are they tested?

3) What is the return merchandise authorization (RMA) process of the manufacturers? 

For example,

  • What happens when there is a defect?
  • Who pays for the product and shipping? 
  • What are the responsibilities on both sides? 
  • Will, there be a corrective action for every defect?
  • Or is there a defect-rate threshold that needs to be reached first?
