Problems solved by technology

[0004] However, due to the regularity between the two-layer display modules, when the light passes through the lower display module and exits to the upper display module, there is a fixed light gap between the transmitted light generated by the upper display module and the reflected transmitted light. Because of the distance difference, there will be interference between the light rays, and rainbow patterns will appear subjectively on the display, which will affect the image display effect

Abstract

The invention discloses a display device, comprising: a first display panel, a second display panel located on the light emitting side of the first display panel; a side of the first display panel facing the second display panel and a side of the second display panel facing the first display panel One side of the panel includes a substrate, at least one substrate is provided with a microstructure, and the modulation effect of the microstructure on the optical path of the incident light is used to destroy the fixed optical path difference formed by the light between the two substrates, thereby avoiding the gap between the light Interference, suppress the rainbow pattern on the display surface.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] Liquid Crystal Display (LCD) has the advantages of high image quality, power saving, thin body and wide range of applications, etc., and currently still occupies a dominant position in the display field. The traditional liquid crystal display adopts the form of backlight and liquid crystal display panel, which has great advantages in white field brightness, but is lacking in viewing angle and black field performance. [0003] In order to make up for the defects of liquid crystal displays, a display scheme of a double-layer display module is proposed. The lower display module is used as the backlight of the upper display module, which can achieve pixel-level light control; the upper display module is used for image display, and the double-layer display The module is turned off, which greatly reduces the brightness of the bl...
