Embodiment Construction

[0059] In order to make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Unless otherwise defined, all technical terms used in the embodiments of the present invention have the same meanings as commonly understood by those skilled in the art.

[0060] A liquid crystal display device is a display device that is widely used at present. Such as figure 1 As shown, in the liquid crystal display device, the sub-pixel control of the backlight is realized through the liquid crystal light valve X, that is, the amount of the backlight reaching each pixel layer 6a of the color filter unit is controlled separately. The specific principle is that by controlling the liquid crystal molecules The arrangement direction controls the amount of backlight passing through, thereby controlling the amount of backlight reaching the pixel layer 6a. ...

Abstract

The invention discloses a display device and a preparing method thereof, and belongs to the technical field of displaying. The display device comprises a backlight unit and a color light filtering unit; the backlight unit comprises a light emitting diode LED array, and the LED array comprises multiple LEDs; the color light filtering unit comprises multiple black matrixes and multiple pixel layersformed in gaps between the adjacent black matrixes; one LED corresponds to one pixel layer. According to the display device, the LED array is utilized for replacing a liquid crystal light valve to achieve sub-pixel control over backlight, thus the backlight emitted by the LEDs directly arrives at the color light filtering layer without passing through the liquid crystal light valve, therefore, theproblem that the contrast ratio of the display device is low due to light leakage of the liquid crystal light valve is solved, and then the display device has a great display effect.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device and a preparation method thereof. Background technique [0002] With the development of science and technology, display devices are widely used in daily life and work of consumers, and liquid crystal display devices are widely used display devices in recent years. see figure 1 , which shows the structure of a liquid crystal display device, such as figure 1 As shown, the liquid crystal display device includes: a backlight unit, a color filter unit, and a liquid crystal light valve X arranged between the backlight unit and the color filter unit. The backlight unit includes a reflective sheet 1a, a light guide plate 2a located above the reflective sheet 1a, an LED 4a (Light Emitting Diode) located on the side of the light guide plate 2a, and a collimating film 3a located above the light guide plate 2a. The color filter unit includes a plurality of black matrices...
