Abstract

The invention provides a display module and a display device, relates to the technical field of display, and aims to solve the problems that a reflective liquid crystal display is complex in optical structure, high in cost and the like. The display module comprises an upper polaroid, a display panel, a selective wavelength transmission film, a lower polaroid and a backlight source which are arranged in sequence, the upper polaroid is provided with a first light-transmitting axis and is used for generating polarized light of which the polarization direction is parallel to the first light-transmitting axis; the display panel comprises a liquid crystal display panel; the lower polaroid is provided with a second light-transmitting axis and is used for generating polarized light of which the polarization direction is parallel to the second light-transmitting axis; and the selective wavelength transmission film can transmit target light rays which are emitted by the backlight source and have specific wavelengths. The display module is used for displaying.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display module and a display device. Background technique [0002] Smart wear and electronic price tags are emerging markets with huge potential. Smart wear technology is developing rapidly. However, due to the small size of the device itself, it is difficult to carry large-capacity batteries. Therefore, the reflective liquid crystal display (English: Liquid Crystal Display, referred to as LCD) is in the Smart wearables and electronic price tags are widely used in the market and have great prospects. [0003] However, the above-mentioned reflective liquid crystal display has the problems of complex optical structure and high cost. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a display module and a display device for solving the problems of complex optical structure and high cost of the reflective liquid crystal display. ...
