1. Adopting attached light-absorbing strip to solve the problem that the LED lamp is thicker than the light guide plate


If the LED lamp is directly changed to 0.4mm thickness to adapt to the thickness of the light guide plate, the cost of the backlight will increase by about 20 percent . Moreover, after the LED lamp is changed, whether it can match the light guide plate needs to be tested Therefore, after repeated scrutiny, we chose to add a light-absorbing strip to the lamp socket of the LED lamp on the reverse side of the backlight to raise the light guide plate, so as to adjust the matching degree of the LED lamp and the light guide plate and reduce the generation of glare.


2. Increase the size of the polarizer under the LCD to improve the gap condition


The original 42.1034.40mm polarizer is replaced with a 44.1034.40mm polarizer. After the polarizer is lengthened, the polarizer can completely cover the LED and at the same time fill the gap between the LCD and the LED.


Three, increase the distance of the window


Since the visual area of LE D cannot be performed after the black and white glue is attached, and the standard deviation S after the assembly of the black and white glue is {{0}}.058mm, if the distance between the edge of the AA area of the LED and the edge of the black and white glue is set at 0 during the production process. 0 8 mm space, and calculated based on D2 with a maximum length of 3.4mm, 3.4-0.08-30.058=3.14. Therefore, the distance between the window and the light-emitting surface of the LED lamp is increased from 2.9mm to 3.14mm.


Fourth, strengthen employee training


In view of the problem of glare caused by the operation of employees, it is necessary to continuously improve the rules and regulations, standardize the operation technology, at the same time strengthen the training of operation skills and strengthen the quality education of employees, improve the professional quality of employees, and reduce the waste rate.
