The instruments and household appliances used in daily life, when using this LCD screen, are not as bright as they were at the beginning, becoming a bit blurry or light. What is the reason?
There are generally the following reasons:
The backlight of an LCD screen uses LEDs as the light source. After long-term use, LED attenuation will occur, so it will appear darker.
Solution: Long term illumination of the LCD screen backlight requires a long-lasting LED as the backlight source.
LCD screens should be used at the correct temperature. As is well known, if the room temperature liquid crystal (0-50 ° C) is placed in a high temperature environment (-40-80 ° C), the liquid crystal will quickly experience display problems.
Solution: At the beginning of product design, choose the correct temperature for using the LCD screen and try to choose the width as much as possible!
