A liquid crystal module and its liquid crystal display

Abstract

A backlight module and a liquid crystal display using the backlight module. The backlight module comprises at least: an edge type backlight source (6), a light guide plate (4), an optical membrane group (5), and a light reflecting plate (1). The light guide plate (4) is provided with a light entering surface and a light emitting surface, and the light entering surface directly faces to the edge type backlight source (6). The optical membrane group (5) is located above the light guide plate (4), and directly faces to the light emitting surface of the light guide plate (4). The light reflecting plate (1) is disposed below the light guide plate (4). A bottom of the light reflecting plate (1) is further provided with a heat conducting layer (2) used for at least transmitting heat transmitted by the edge type backlight source (6) to a middle part of the light reflecting plate (1). In this manner, a temperature of a central position of a display panel (7) of a liquid crystal module can be improved, so that a phenomenon of crosstalk caused by the excessively low temperature of the central position of the display panel (7) of the liquid crystal module can be reduced or eliminated; and the existing liquid crystal module does not need to be greatly changed, so that the expenditure is low.

Description

technical field [0001] The invention relates to thin film transistor liquid crystal display (ThinFilmTransistorLiquidCrystalDisplay, TFT-LCD) technology, in particular to a liquid crystal module and a liquid crystal display thereof. Background technique [0002] At present, the backlight of most TFT-LCD liquid crystal modules mainly adopts two types: edge type (Edge type) and direct type (direct type). More and more TFT-LCD adopts side-lit LED backlight design. [0003] However, when the side-lit LED backlight is used in the liquid crystal module, there are some disadvantages. For example, the temperature at the center of the display panel (Panel) of the display module of the liquid crystal module may be relatively low. If the display panel The temperature at the center is relatively low, which will affect the display effect of the picture, especially when displaying 3D pictures, it is easy to generate crosstalk (crosstalk). [0004] In view of the crosstalk phenomenon cau...

Problems solved by technology

[0003] However, when the side-lit LED backlight is used in the liquid crystal module, there are some disadvantages. For example, the temperature at the center of the display panel (Panel) of the display module of the liquid crystal module may be relatively low. If the display panel The temperature at the center is low, which will affect the display effect of the picture, especially when displaying 3D pictures, it is easy to produce crosstalk (crosstalk)

[0004] In view of the crosstalk phenomenon caused by the low temperature in the center of the display panel, in the prior art, the internal structure of the display panel and the corresponding driving circuit are usually improved to overcome this deficiency, such as changing the photomask, but this method will increase the structure Complexity, and at the same time increase the cost, unfavorable for cost-optimized design
