Embodiment 1

[0026] This embodiment provides a liquid crystal display module capable of selectively switching between a normally black mode and a normally white mode. Such as figure 1 As shown, the liquid crystal display module includes a liquid crystal panel 1 , a backlight module 2 and a liquid crystal panel driving module 3 .

[0027] Wherein, the liquid crystal panel 1 includes a thin film transistor array substrate 12 and a color filter substrate 13 arranged oppositely, and also includes a liquid crystal layer 14 arranged between the thin film transistor array substrate 12 and the color filter substrate 13, and the color filter A third polarizer 11 is also disposed on the substrate 13 (that is, the third polarizer 11 is located on the light emitting side of the liquid crystal panel 1 ).

[0028] Wherein, the backlight module 2 is an edge-type backlight module, which includes a plurality of first light sources 21, a plurality of second light sources 22, and a light guide plate 23, and...

Embodiment 2

[0041] The difference between this embodiment and Embodiment 1 is that the backlight module in the liquid crystal display module provided by this embodiment includes two light guide plates. Specifically, see Figure 5 , the liquid crystal display module provided in this embodiment also includes a liquid crystal panel 1 , a backlight module 2 and a liquid crystal panel driving module 3 . Wherein, the backlight module 2 includes a first light guide plate 23a and a second light guide plate 23b arranged in layers, the first light source 21 is set on the side of the first light guide plate 23a, and the second light source 22 is set on the second side of the light guide plate 23b. It should be understood that there are multiple first light sources 21, and multiple first light sources 21 may be disposed on any side or multiple sides of the first light guide plate 23a. Similarly, there are multiple second light sources 22, and multiple second light sources 22 may be disposed on any ...

Embodiment 3

[0044] The difference between this embodiment and Embodiment 1 is that the backlight module in the liquid crystal display module provided by this embodiment is a direct type backlight module. Specifically, see Image 6 , the liquid crystal display module provided in this embodiment also includes a liquid crystal panel 1 , a backlight module 2 and a liquid crystal panel driving module 3 . Wherein, the backlight module 2 includes a diffuser plate 26, a plurality of first light sources 21 and a plurality of second light sources 22 are arranged under the diffuser plate 26, and the first light sources 21 and the second light sources 22 are alternately spaced apart. cloth. Image 6 Only three first light sources 21 and three second light sources 22 are exemplarily shown in FIG. That is, a first polarizer 24 is disposed between each first light source 21 and the light guide plate 23 , and a second polarizer 25 is disposed between each second light source 22 and the light guide plat...

Abstract

The invention discloses a liquid crystal display module. The liquid crystal display module comprises a liquid crystal panel, a backlight module and a liquid crystal panel drive module, wherein third polarizers are arranged on the light-emitting side of the liquid crystal panel; the backlight module comprises multiple first light sources and multiple second light sources, a first polarizer is configured on the light-emitting surface of each first light source, and a second polarizer is configured on the light-emitting surface of each second light source; the polarization direction of each first polarizer is vertical to that of each second polarizer, and the polarization direction of each third polarizer is identical to that of each first polarizer or each second polarizer. The liquid crystal panel drive module comprises a first data signal driver and a second data signal driver. When the first light sources are started, the first data signal driver provides data signals for the liquid crystal panel, and when the second light sources are started, the second data signal driver provides signals for the liquid crystal panel.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display module. Background technique [0002] The liquid crystal display is divided into normally white mode and normally black mode. When the backlight is turned on and the LCD panel is not powered on, the display is in a bright state, which is the normally white mode. model. Normally, only one of the normally white mode and the normally black mode can be selected for a liquid crystal display. When most parts of the LCD panel are in a bright state, the normally white mode has the advantage of saving power consumption. Using the normally black mode when some parts are in the dark state has the advantage of saving power consumption. Specifically, for example, when watching a novel, the screen background is white and the text is black. At this time, choosing the normally white mode can save power consumption, because the white background that occup...
