Embodiment Construction

[0011] refer to figure 2 , figure 2 It is a schematic structural diagram of the liquid crystal display 50 in the first embodiment of the present invention. Such as figure 2 As shown, the liquid crystal display 50 includes a backlight assembly 52 and a liquid crystal display panel 54 . The backlight assembly 52 includes an optical film 58 disposed above a light source 56, wherein the light emitting element forming the light source 56 can be a cold cathode tube (Cold Cathode Fluorescent Light, CCFL), a hot cathode lamp, or a cold cathode lamp with external electrodes. Or cold cathode flat fluorescence lamp (cold cathode flatfluorescence lamp, CCFFL). The liquid crystal display panel 54 includes a plurality of pixel units (not shown) and is disposed above the optical film 58 . In addition, a reflective plate 57 is disposed under the light source 56 for reflecting the light generated by the light source 56 upwards, so as to provide better brightness output of the liquid cry...

Abstract

The LCD device includes one back light unit and one LCD panel. The back light unit includes one optical film set over the light source and including at least one vacuum layer. The LCD panel is set over the optical film and includes several pixel units. The vacuum layer is used in isolating heat the light source produces.

Description

technical field [0001] The present invention relates to a liquid crystal display (liquid crystal display, LCD). Background technique [0002] Due to the low price and high quality of liquid crystal displays, liquid crystal displays have been widely used in information products such as notebook computers (notebooks), personal digital assistants (PDAs), mobile phones, clocks, TVs, digital cameras, and digital cameras. . Generally speaking, a liquid crystal display is composed of a display panel and a backlight unit. The backlight unit is arranged under the display panel and includes a light source and an optical film. film) to provide a uniformly dispersed light to the display panel, and then display appropriate images through each pixel unit on the display panel. Wherein, the direct-lit backlight assembly, in which the light source is generated directly below the display panel, can be applied to liquid crystal displays with higher brightness requirements or larger sizes, su...
