Embodiment Construction

[0030] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail the preferred embodiments of the present invention and the accompanying drawings.

[0031] See Figure 5 to Figure 7 , The present invention provides a display device based on a double-layer liquid crystal Fabry-Perot filter module, comprising: a backlight module 4 and a double-layer liquid crystal Fabry-Perot filter module 2 located above the backlight module 4 , The backlight module 4 provides continuous spectrum white transmitted light for the double-layer liquid crystal Fabry-Perot filter module 2, and the double-layer liquid crystal Fabry-Perot filter module 2 is used for color modulation to Controlling the color and intensity of the transmitted light avoids the use of polarizers and color filters in the existing traditional liquid crystal display device, thereby improving the light utilization rate of the backlight module 4.

Abstract

The invention provides a display device based on a double-layer liquid crystal Fabry-Perot filter module. The display device comprises a backlight module (4) and the double-layer liquid crystal Fabry-Perot filter module (2) arranged above the backlight module (4). A plurality of main pixels (402) are arranged on the double-layer liquid crystal Fabry-Perot filter module (2) in an array distribution mode, each main pixel (402) comprises two auxiliary pixels (204), each auxiliary pixel (204) comprises an upper-layer liquid crystal Fabry-Perot filter module (202) and a lower-layer liquid crystal Fabry-Perot filter module (240), and the two auxiliary pixels (204) of each main pixel (402) are driven independently, so that white transmission lights with continuous spectrum provided by the backlight module (4) can form transmission lights with two chroma when transmitting the two auxiliary pixels (204), and the chroma of the main pixels (402) can be obtained when the transmission lights with the two chroma are mixed.

Description

Technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a display device based on a double-layer liquid crystal Fabry-Perot filter module. Background technique [0002] Liquid Crystal Display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used, such as mobile phones, personal digital assistants (PDA), digital cameras, computer screens or laptop screens Wait. [0003] Most of the liquid crystal display devices currently on the market are backlight type liquid crystal display devices, which include a housing, a liquid crystal panel arranged in the housing, and a backlight module arranged in the housing. The structure of the traditional liquid crystal panel is composed of a color filter substrate (Color Filter), a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate), and a liquid crystal layer (Liquid Crystal Layer) arranged bet...
