Description

Liquid Crystal Display Structure and Electronic Devices

technical field

The utility model relates to the field of electronic products, in particular to a liquid crystal display structure and electronic equipment.

Background technique

The traditional liquid crystal display uses acrylic plexiglass as the substrate, and the microstructure is made on the acrylic surface by injection molding or printing. On the liquid crystal display, one piece is incorporated into an iron frame, and the iron frame supports all devices to form a single liquid crystal display.

For the light guide plate of traditional liquid crystal displays, due to the limitation of the mechanical strength of acrylic itself and the injection molding technology, the microstructure of the light guide plate of 9-17 inches can only be made with a thickness of more than 0.6mm, and the injection molding of less than 0.6mm will Seriously affect the flatness and yield. The other type uses flat acrylic as the base material to make the microstructure by printing. However, due to the limited mechanical strength of the acrylic plate, it cannot be made into a light guide plate with high flatness.

All the components of the traditional liquid crystal display are contained and supported by an external iron frame. The iron frame has no luminous effect and only plays a supporting role, which increases the thickness and cost of the entire liquid crystal display.

Part of it is bonded to the reflection sheet 5.

The utility model uses glass as the light guide plate. While reducing the thickness, the mechanical strength is still higher than that of the thicker acrylic plate; therefore, except for the liquid crystal display, all other components can be directly combined with the glass light guide plate without an iron frame.
