Are you confused and want to know how to select the right and perfect components for your custom LCD module?

No need to worry; you are on the right page. Today we will discuss the right components like the backlight, temperature range, size, and type of the display for the custom display module. It will assist you in knowing how to customize your item in 2-3 months while saving the general expense of your item. We are hoping after reading this article you would be able to make the right decision.

1. Understand Your Customer’s Expectations

First, you need to understand your customer’s expectations from your product or services. We have seen many technological improvements in the display module space, such as monochrome custom LCD, TN, and FSTN LCDs and various functionality enhancements that can be done perfectly. It may be difficult for you to understand the benefits of all displays in this fast-paced world with many technological improvements. Unfortunately, everyone wants their product without knowing its pros and cons and a proper understanding of the technology.

Do you take the time to understand what you need or what you want to see in your product?

Many companies primarily establish only a particular display module without understanding whether other options may better suit their needs; they don’t thoroughly evaluate the customer’s expectations and result in under-performing or over-engineered products.

These factors significantly affect the cost, design cycles, and user experience. For example, the optical bonding of cover lenses sounds like a must-have is a mistake, as it may not always be required.


 Answer To Some Important Questions 

To get a clear understanding, you need to answer the following questions in detail. All companies need to ask these questions before engaging in a display project, and These questions are as simple as:

2. What Are The Types Of Custom LCDs?

There are many types of Liquid crystal displays that you can choose from. Some are modern technology, and others are older types of displays.


There are some categories, and types of the LCD are:

Monochrome can be divided into:

  • Graphic LCD
  • Segment LCD


  • CSTN(Kind of STN)
  • TFT
  • Silk-Printing for monochrome LCD(TN, HTN, STN, FSTN, DSTN, VA)

3. What Type And Size Of Display Do You Need?

Custom LCD screens are available in various sizes ranging from tiny digital watches to enormous televisions. They are also used as glass or plastic panels, where LCDs use two glass panels.

You can measure the size in inches from corner to corner, and almost any size is available. The largest LCD we can make is 460*360mm because the whole glass panel size is 470*370mm.

There is a higher interest in a small custom LCD Display module. At present, the minimum size of the display can reach 10*10mm that we have designed and mass-produced.


4. Do You Need A Reflective Or Transmissive Or Transflective Display?

Polarizer displays have three types, including reflective, transmissive, and transflective and you need to choose from them, as they are different.

  • Transmissive LCD 

It is always combined with a backlight, although it can be used without a backlight we generally don’t recommend this. 

  • Reflective LCD 

It does not have a backlight because its bottom film does not transmit light and the contents on the screen can only be seen with the external light source.

  • Transflective LCD 

It is a combination of both transmissive and reflective technologies so it can be used without backlight or with backlight.


5. What Functionality Are You Expecting?

You should be clear about the functionality you are expecting from your display. A liquid crystal display is an electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. LCDs use a backlight to produce images in monochrome or color as they do not emit light directly.


6. What Type Of Interface Is Needed For Your Product?

We divided the interface of LCD into 3 kinds. Pin assignment, conductive tape, and FPC.

If the LCD is small and not enough space for the connection to the PCB, we will choose conductive tape for it.

If there is enough space for connection, we will choose pin assignment or FPC. It can be determined by the product’s frame.

If there are so many icons and symbols in the LCD, we will choose FPC for it, then it will be a COF frame. Because it needs an extra IC to drive.

If the IC is on the board, there will be so many ways for the connection. PIN assignment, conductive tape, or FPC all can be. (Yes, FPC also can be, because the FPC can be treated as a flexible way for the frame, and IC can be on the board, FPC as an extended part of the connection.)


7. What Level Of Backlight Brightness Do You Need?

Generally speaking, when the size is fixed, the higher the brightness required, the higher the thickness of the backlight will be because brighter lamp beads are used.

If the thickness is fixed, then another way to increase the brightness is to increase the size of the backlight so that more lamp beads can be added.

The third way is to change different led beads, there are many different led beads for backlights. Like Philip, Samsung, etc.


8. Does your display module need a touch panel?

A touch panel is a piece of equipment that lets users interact with an LCD module by touching the screen directly. Incorporating features into the monitor like sensors that detect touch actions makes it possible to issue instructions to a device by having it sense the position of a finger. A touch panel can be a resistive touch panel or a capacitive touch panel.

Normally, a monochrome LCD doesn’t need a touch panel. TFT LCD will need a touch panel.


9. What Is Your Operating Temperature Range?

Generally speaking. We divided temperature ranges into 4 tiers.

First, the working temperature is 0 to 50 degrees, storage temperature is -10 to 60 degrees.

Second, the working temperature is -10 to 60 degrees, storage temperature is -20 to 70 degrees.

Third, the working temperature is  -20 to 70 degrees, storage temperature is -30 to 80 degrees.

Forth, the working temperature is -30 to 80 degrees, storage temperature is -40 to 90 degrees.

And it’s clear that the price is from low to high. You need to choose from them for your custom display module. 


10. Do You Need An Extra Layer Of Protection From A Glass Cover Lens?

You should be clear about the protection level of the required display. You need to know clearly whether your display needs an extra layer of protection from a glass cover lens or not. If yes then go for it. 

The above list is not a complete list of questions but food for thought – enough to move the design process on solid ground.

These fundamental questions help display module manufacturers quickly whittle the choices to a handful. This does not mean that further adjustments are not required, but it makes the process of choosing the correct display smoother and less cumbersome.

12. Conclusion

A custom segment display LCD can assist you with customizing your item while likewise saving the general expense of your item. The entire cycle will take you around 2-3 months, which will incorporate the planning stage, prototyping stage, and getting your custom fragment LCDs conveyed to your doorstep.
