  • Please place it in the dark to avoid bright light.
  • Never press anything on the surface of the LCD to prevent any damage.
  • Strictly avoid storage in an environment with humidity and temperature exceeding the limit.

3. Important Things For Use Of LCD Screen You Should Know

Please read the following reminders carefully before using LCD to avoid excessive damage!

When the power is off, make sure to unplug the cable.

  • To ensure the safety and stability of the electrical part, the interval between each turn on and turn off should not be less than 6 seconds.
  • The LCD screen is a very fragile glass product; Any drop, knock, or strong vibration may cause the glass to break.
  • Do not press hard on the LCD area or never force the LCD screen and border when installing.
  • You Should pay attention to the overall flatness of the LCD screen to avoid bending or distortion.
  • Since the visual characteristics of the LCD screen will change depending on the viewpoint, the user’s mindset should be fully considered during the assembly to adjust the optimal view of the LCD screen.
  • In use or storage, don’t put hard objects on the LCD, be careful of the surface polarizer of the LCD screen to avoid scratches by hard things.
  • The inverter part contains high voltage in the drive circuit of the display. Please do not contact during operation to avoid unnecessary damage. 
Storage-Of-Industrial-LCD-Screen
  • The LCD screen works and stores under the specified temperature range. Suppose the liquid crystal is operated and stored in a temperature range above the specified temperature. In that case, it may become isotropic liquid leading to crystal formation and unrecoverable damage and thus unable to recover its liquid crystal state. Please save and use the display within the allowed temperature range.
  • The product is a wide voltage direct current (DC) input, suitable for direct current (DC) 12V switching power supply. The display brightness may be reduced if the input voltage is less than 12V.
  • There are electronic components on the back of the LCD in the driving part of the circuit. It is necessary to avoid damage during the design, assembly, and dispatching process.
  • Keep the surface of the LCD screen clean during storage and use. If water droplets stay on the LCD screen for a long time, they may cause stains or discoloration on the surface of the LCD screen. Therefore, when the screen surface has pigments, use cotton or a soft cloth to wipe. 
  • Do not use alcohol, gasoline, or other chemicals to wipe or clean the LCD screen.
  • After use, turn off the device’s power in time.
  • Please do not place the device in a wet place to prevent fire or electric shock.
  • Avoid exposing the LCD module to ultraviolet light or direct sunlight for a long time.
  • If the screen is damaged and the LCD touches your hands or clothes, please wash it with soap and water.
  • The liquid crystal module adopts CMOS-less, so it must have good anti-static protection when dealing with the liquid crystal module.
  • The LCD and instructions are constant upgrades and modifications without prior notice to enhance performance.

4. Do not pull the backlight wire forcibly to avoid damaging the wire during the operation.

5. It is advised that the operator should wear anti-static clothing and a grounding wristband when contacting the LCD module.

6. If the external lead of the liquid crystal module is connected wrong, it may cause overpressure, overcurrent, and other damage to the module device.

7. When the module utilizes the access power source and disconnects, the signal level can only be input after the positive power source, which is 5± 0.25v stably connected. The IC circuit of the module may be damaged if the signal level is input before or after the power supply is stabilized.

8. Press forcefully on the display area will cause an abnormal display. After recharging, disconnect the power supply, and return to normal.

  • Obsolescence
  • Delivery
  • Quality
  • Performance
  • Cost

But why would you ever call us? 

Here’s how you can successfully address and resolve the above 5 LCD challenges.

In order of occurrence, these are the only five reasons to contact us:

What-are-the-five-key-LCD-display-challenges-you-can-face?

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.

Cost
