Abstract

The embodiment of the invention discloses a reflective display screen device. The reflective display screen device comprises a display screen, a thin film transistor backboard, a composite light guide module, a front light unit and a first adhesive layer. The thin film transistor backboard is used for reflecting light. The composite light guide module is located between the display screen and the thin film transistor backboard and comprises a first light guide layer and a second light guide layer, the second light guide layer is located between the first light guide layer and the thin film transistor backboard, the first light guide layer and the second light guide layer have different refractive indexes, and the first light guide layer and the second light guide layer are provided with lattice point structures. The front light unit is arranged on one side of the composite light guide module. The first adhesive layer is located between the display screen and the first light guide layer. The device has the advantage that the light total reflection effect required by the reflecting screen can be greatly improved under the condition that the design complexity is not increased.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a reflective display screen device suitable for terminal equipment. Background technique [0002] With the continuous development of communication technology, terminal products such as smart phones, tablet computers and notebook computers have become indispensable products in daily life. Terminal products are developing in the direction of diversification and individualization. People can work and entertain through terminals, such as reading through terminals to obtain the latest news. These electronic devices are equipped with displays, including liquid crystal screens (Liquid Crystal Display, LCD), active-matrix organic light-emitting diodes (Active-matrix organic light-emitting diode, AMOLED), etc., and LCD, AMOLED and other displays need backlight or self-illumination The light source can be turned on, and the blue light carried by the light source is harmful to h...
