[0030] First embodiment

[0031] Please refer figure 1 , The liquid crystal display device of the first embodiment of the present invention includes a display panel 10, a first dimmer 20 and a second dimmer 30, the first dimmer 20 and the second dimmer 30 are provided on the same part of the display panel 10. Side, specifically, the first dimmer 20 is located between the display panel 10 and the second dimmer 30. The first dimmer 20 is used to collect light in the up and down direction, and the second dimmer 30 is used to collect light in the left and right directions. The first dimmer 20 includes a first substrate 202, a first electrode 203, a second substrate 205, a second electrode 206, and a first liquid crystal layer 208. The first electrode 203 is provided on the first substrate 202, the second electrode 206 is provided on the second substrate 205, the first liquid crystal layer 208 is sandwiched between the first electrode 203 and the second electrode 206, the first elect...

Example

[0051] Second embodiment

[0052] Such as Figure 7 As shown, the structure of the second embodiment of the present invention is similar to that of the liquid crystal display device of the above-mentioned first embodiment, except that in the second embodiment, the first dimmer 20 and the second dimmer 30 are respectively Located on both sides of the display panel 10.

Example

[0053] The third embodiment

[0054] Such as Picture 8 As shown, the structure of the third embodiment of the present invention is similar to that of the liquid crystal display device of the above-mentioned first embodiment. The difference is that, in the third embodiment, the liquid crystal display device only includes the first dimmer 20. , The liquid crystal display device can only realize the upper and lower narrow viewing angle display mode and the wide viewing angle display mode. It can be understood that, in another embodiment, the liquid crystal display device may only include the second dimmer 30. In this case, the liquid crystal display device can only implement a left and right narrow viewing angle display mode and a wide viewing angle display mode.

Abstract

The invention discloses a liquid crystal display device and a driving method thereof. The liquid crystal display device comprises a display panel and a first light modulator. The first light modulatoris arranged on one side of the display panel. The first light modulator is used for receiving light and comprises a first electrode, a second electrode and a first liquid crystal layer. The first liquid crystal layer is clamped between the first electrode and the second electrode, the first electrode is closer to a light emitting side of the liquid crystal display device than the second electrode, and the second electrode is divided into at least two sub-electrodes. According to the liquid crystal display device and the driving method thereof provided by the invention, wide-viewing-angle andnarrow-viewing-angle display can be realized by arranging the first light modulator, a penetration rate and a contrast ratio of front view are not influenced in a narrow-viewing-angle mode, and a display effect is good; moreover, the second electrode is divided into the plurality of sub-electrodes so that different voltages can be applied to the sub-electrodes, areas corresponding to the differentsub-electrodes are displayed in different display modes, and wide and narrow viewing angle partition display of the liquid crystal display device is realized.

Description

technical field [0001] The invention relates to the field of liquid crystal display technology, in particular to a liquid crystal display device and a driving method thereof. Background technique [0002] Liquid crystal display devices have the advantages of good image quality, small size, light weight, low driving voltage, low power consumption, no radiation, and relatively low manufacturing costs, and occupy a dominant position in the field of flat panel displays. [0003] With the continuous advancement of liquid crystal display technology, the viewing angle of the display has been expanded from about 120° to more than 160°. While enjoying the visual experience brought by the large viewing angle, people also hope to effectively protect commercial secrets and personal privacy. In order to avoid commercial loss or embarrassment caused by leakage of screen information. Therefore, in addition to the wide viewing angle, the display device is also required to have the function...
