Reflective display substrate and reflective display device

Abstract

The invention discloses a reflective display substrate and a reflective display device, and relates to the display fields. The display function can be achieved without using liquid crystal. The reflective display substrate comprises a reflecting layer, a stress birefringence layer, a quarter-wave plate layer and a light polarizing layer which are sequentially overlapped, wherein the stress birefringence layer comprises multiple stress birefringence pieces arranged in an array mode, natural light becomes circularly polarized light after penetrating through the light polarizing layer and the quarter-wave plate layer, and when the stress birefringence layer deforms, the circularly polarized light penetrating through the stress birefringence pieces becomes elliptically polarized light. The reflective display substrate further comprises multiple deformation generating mechanisms, and each deformation generating mechanism is connected with the corresponding stress birefringence piece. The reflective display substrate and the reflective display device are suitable for reflective display.

Description

technical field [0001] The invention relates to the display field, in particular to a reflective display substrate and a reflective display device. Background technique [0002] Such as figure 1 As shown, the existing reflective display device includes a liquid crystal panel 11, and the liquid crystal panel 11 includes a color filter substrate 12 and an array substrate 13, wherein the color filter substrate 12 includes a first substrate 121, a first conductive layer 122 and an The first alignment layer 123 and the array substrate 13 include the second substrate 131 , the second conductive layer 132 and the second alignment layer 133 which are sequentially stacked. In addition, the liquid crystal layer panel 11 also includes a layer arranged between the color filter substrate 12 and the array substrate 13 The liquid crystal layer 114 between them, and the reflective layer 4 disposed on the outer surface of the array substrate 13 . [0003] When the reflective display device...

Problems solved by technology

[0004] However, since the existing reflective display devices rely on the physical properties of liquid crystals to achieve display, there must be the following problems: the purity of the liquid crystal solution used in the liquid crystal filling process during the preparation of the liquid crystal panel 11 is not enough, or the liquid crystal solution is polluted during the operation process. , resulting in more impurities in the liquid crystal layer 114, which affects the display quality; due to the limited service life of the liquid crystal, the service life of the reflective display device is limited; because the liquid crystal will be deactivated at high temperature, the use environment of the reflective display device is limited
