How To Control The Tolerance Of The Backlight Light Guide Plate
Dec 24, 2021
The tolerance of the backlight is mainly determined by the light guide plate, and there are two kinds of light guide plates, one is injection molding and the other is silk-screen printing plate. The precision of the template is relatively high, because it is from the mold. It is made of injection molding. Therefore, if customers have high requirements for product accuracy, they will generally use an open template as the backlight because of its high accuracy, but also high requirements for quantity. The accuracy of the silk-screen board is slightly lower than that of the injection mold. The main reason is these factors, but its MOQ requirement is not as high as that of the injection-molded board, so customers now generally use the silk-screen board:
The accuracy of the cutting machine itself
1. The belt impact of the cutting machine.
2. The speed of the cutting machine and the power of the laser cutting machine
3. Batch distribution of cutting machine software and hardware
Second, the accuracy of the acrylic material
1. Acrylic is divided into two types: extruded sheet and phantom sheet. Generally, the precision of extruded sheet is higher than that of phantom sheet.
Third, the method of cutting and adjusting the machine
Fourth, the flatness of the machine.
