Embodiment 1

[0053] In the present invention, Embodiment 1 of colorizing the lens-type dimming device is as follows: figure 2 As shown, in this embodiment 1, the colorization of the entire dimming device is realized by colorizing the droplet lens.

[0054] Specifically, three droplet lenses are set in one pixel unit, and the three droplet lenses are colored into three colors of red (R), green (G), and blue (B) respectively (because the colors cannot be displayed in the drawings ,exist figure 2 The middle oblique stripes indicate that the area is red, the vertical stripes indicate that the area is green, and the horizontal stripes indicate that the area is blue; the stripes in the following figures are the same as figure 2 The meaning is the same in the above, and will not be described in detail below), and the color and brightness displayed on a pixel unit are obtained through the combination of three colors of different intensities passing through the light. A color display panel wit...

Embodiment 2

[0056] In the present invention, Embodiment 2 of colorizing the lens-type dimming device is as follows image 3 As shown, in this embodiment 2, the colorization of the entire dimming device is realized by placing color filters. The position of the color distribution (for example, the position of R, G, B distribution) corresponds to the droplet lens.

[0057] Specifically, a color filter is placed between the top electrode and the baffle, or a color filter is placed outside the baffle, similar to the TFT-LCD array substrate, and a pixel unit on the color filter is provided with red, There are three sub-pixel units of green and blue, and each sub-pixel unit corresponds to a droplet lens. The light transmitted by the droplet lens is filtered into the light of the corresponding color, which is obtained by combining the transmitted light of three colors with different intensities. The color and brightness displayed on a pixel unit. A color display panel with corresponding resolut...

Embodiment 3

[0059] In the present invention, Embodiment 3 of colorizing the lens-type dimming device is as follows Figure 4 As shown, in the third embodiment, the colorization of the entire dimming device is realized by colorizing the light-transmitting area of ​​the baffle. The colored colors are distributed in the light-transmitting area of ​​the baffle, and each light-transmitting area of ​​the baffle is divided into two colors, and the same color is set on both sides of each light-shielding area 201 . And the overall position of each color corresponds to the droplet lens. Optionally at this time, the area of ​​the light-shielding region 201 of the baffle is smaller than the area of ​​the corresponding droplet lens.

[0060] Specifically, similar to Embodiment 2, filters of various colors are arranged in the light-transmitting area of ​​the baffle, and three sub-pixel units of red, green, and blue are formed in one pixel unit on the baffle, and each sub-pixel unit is connected with ...

Abstract

A dimming device and a display. The dimming device comprises a lens screen (1) and a blocking plate (2). The blocking plate (2) is disposed at a light exiting side of the lens screen (1) and opposite to the lens screen. The lens screen (1) comprises a bottom electrode (3), a top electrode (5), and a liquid between the bottom electrode and the top electrode. The liquid can form at least one droplet lens (4). The blocking plate (2) comprises a light blocking region (201) and a light transmitting region (202). The dimming device can adjust light without arrangement of any polarizer, thereby improving the utilization rate of backlight.

Description

technical field [0001] The invention relates to the technical field of dynamic dimming, in particular to a dimming device and a display. Background technique [0002] The traditional liquid crystal display is usually a passive light-emitting transmissive display. The light emitted by the backlight enters from one end of the liquid crystal panel. After being selected by the first polarizer, the light in a specific direction enters the liquid crystal layer for processing. After processing, each pixel unit displays The light is selected by the second polarizer and then output. It can be seen that due to the need to use polarizers in liquid crystal displays, most of the light emitted by the backlight will be filtered out during transmission. At the same time, the aperture ratio of each layer in the liquid crystal panel is limited, resulting in a very low overall light transmittance. Under normal circumstances, the light transmittance of a color LCD panel is only 5% to 8%. This...
