Problems solved by technology

[0004] However, the current designs of liquid crystal displays on the market only consider the match between the diffuser and the backlight module, that is, whether the diffuser can provide a uniform surface light source for the backlight module, but do not consider the relationship between the diffuser and the LCD. Matching fit between panels
Therefore, when the matching between the diffusion sheet and the display panel does not match, the phenomenon of display unevenness (mura) will occur in the liquid crystal display, thereby reducing the visual effect of the user when viewing the liquid crystal display.

Embodiment Construction

[0064] figure 1 It is a schematic cross-sectional view of a display according to an embodiment of the present invention. Please refer to figure 1 , in this embodiment, the display 100 a includes a display panel 110 a, a backlight module 120 and a diffusion sheet 130 . In detail, the display panel 110a is composed of an active device array substrate 115, a pair of facing substrates 117 and a display medium layer 119, wherein the active device array substrate 115 has a display area 113a and a non-display area surrounding the display area 113a. The area 113b and a plurality of pixel units 115a, and each pixel unit 115a has an opening 116, and the opening 116 is located in the display area 113a. In addition, the display panel 110a has an upper surface 111a and a lower surface 111b opposite to each other. The opposite substrate 117 is, for example, a color filter substrate, and the display medium layer 119 is, for example, a liquid crystal layer, but not limited thereto.

Abstract

The invention discloses a display, which comprises a display panel, a backlight module and a diffusion sheet, wherein the display panel is provided with a plurality of pixel units; each pixel unit is provided with an opening; the backlight module is arranged below the display panel; the diffusion sheet is arranged between the display panel and the backlight module and comprises a diffusion layer;the diffusion layer is provided with a plurality of diffusion particles; and the ratio of the size of the opening of each pixel unit to the particle size of each diffusion particle is more than or equal to 2. According to the display disclosed by the invention, a good visual effect can be achieved when a user watches the display.

Description

technical field [0001] The present invention relates to a display, and in particular to a display with better display effect. Background technique [0002] The rapid progress of the multimedia society is mostly due to the rapid progress of semiconductor components or display devices. As far as displays are concerned, liquid crystal display devices (LCD devices) with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation have gradually become the mainstream of the market. [0003] Generally speaking, a liquid crystal display mainly includes a backlight module, a liquid crystal display panel, an upper polarizer and a lower polarizer. The backlight module is arranged under the liquid crystal display panel to provide the backlight required by the liquid crystal display panel. The upper polarizer and the lower polarizer are respectively arranged on the upper surface and the lower surface of the liquid crys...
