Factors affecting the color difference of TFT screens

2022-12-09

Some customers have given us feedback on why the tft screen produced by the same manufacturer has color difference? TFT screen # ili9488 tft lcd # color difference usually refers to two tft screens put together, the color difference is not the same, if the range of color difference is usually unacceptable to the customer, today I will talk with you about the factors affecting the tft screen color difference?

 

         

1. Glass from different panel manufacturers Different batches of glass produced by different panel manufacturers have different colors after being cut into pieces. At present, our big factory glass includes BOE, AUO, Innolux Corporation, etc. The panels produced by each manufacturer have color difference when they are finally assembled into tft screens  # 3.5 inch TFT 320x480 #.


2.The main component of backlight batches of different backlights is led lamp bead, and this is the most important component of the display screen, and led white light is composed of three colors, which is commonly known as RGB. The left-right value of the wavelength of light will produce LED optical reaction, directly causing small changes in the display effect of the LCD panel. Resulting inTFT screen  # 7 inch capacitive touch display # color difference.


3.Polarizing film is a kind of multi-layer polymer material composite, with polarized light function of the optical film, according to its use in the LCD screen  # pantalla TFT LCD 1.54 # is different, generally can be divided into two kinds of film and film, it mainly has, polarizing layer, TAC layer, adhesive, peel film, protective film, reflection film, and polarizing film will be different Angle refraction color, The display effect will also vary, so the polarizers produced in different batches and the different angles rotated according to different batches of polarizers in each production will affect the final result.


4.voltage:

Since the voltage of different batches of glass substrate will fluctuate ±0.5V from the factory, we will try our best to adjust the output voltage to be consistent during production, but it is difficult to achieve complete consistency. Therefore, we usually recommend customers to add the function of contrast adjustment in software or hardware.

It can be seen that the display effect of different batches of LCD screens is related to many aspects, andTFT screen # 3.5 inch LCD TFT MCU # manufacturers will help customers take these factors into account. We will try our best to meet the same color of the same batch according to the customer's requirements.


Therefore, when purchasingTFT screens, we should pay attention to communicate withTFTscreen manufacturers in advance about the color range, which range can be accepted.
