Embodiment 1

[0046] Embodiment 1 of the present invention provides a method for controlling the viewing angle of a liquid crystal display, which is applied to a liquid crystal display panel. The liquid crystal display panel includes an array substrate and a color filter substrate arranged in opposite boxes. The method includes: in the color filter substrate of the liquid crystal display panel The first planar transparent electrode is arranged, and the second strip-shaped transparent electrode is arranged in the array substrate of the liquid crystal display panel, so as to pass through the first planar transparent electrode and the second strip-shaped transparent electrode, between the array substrate and the second strip-shaped transparent electrode. A fringe electric field is formed between the electrodes arranged on the color filter substrate; by controlling the formed fringe electric field, the display viewing angle of the liquid crystal display panel is controlled.

[0047] The array su...

Embodiment 2

[0069] In order to make better use of the fringe field effect, make the cross-section of the liquid crystal molecules the same in all directions, so that the light in all directions can be uniformly compensated, and improve the aperture ratio and light transmittance of the entire liquid crystal display panel, it can be used on the TFT array substrate Two layers of strip-shaped transparent electrodes are arranged in the middle, and the viewing angle of the liquid crystal display panel is controlled according to the fringe electric field formed between the two layers of strip-shaped transparent electrodes and the planar transparent electrodes arranged in the color filter substrate.

[0070] Embodiment 2 provides a method for controlling the viewing angle of a liquid crystal display. Electrodes are arranged in the TFT array substrate and the color filter substrate to form a fringe electric field. Specifically, a first planar transparent electrode is arranged in the color filter sub...

Embodiment 3

[0087] Based on the same or similar principle as the above-mentioned method embodiment, Embodiment 3 of the present invention provides a liquid crystal display panel capable of changing the display viewing angle, wherein the structure of the liquid crystal display panel is the same as that shown in FIGS. Figure 8 The structure of the liquid crystal display panel shown in is the same or similar. And based on the same or similar principle, the liquid crystal display panel can realize the adjustment of the display viewing angle.

[0088] An embodiment of the present invention also provides a liquid crystal display, which includes the liquid crystal display panel in the above embodiment, and the liquid crystal display further includes a driving circuit for driving the display of the liquid crystal display panel. Based on the same or similar principle as the above liquid crystal display panel embodiment, the driving circuit can apply a corresponding voltage to each transparent ele...

Abstract

The invention discloses a liquid crystal display viewing angle controlling method, a liquid crystal display panel and a liquid crystal display. The method is used for the liquid crystal display panel including an array substrate and a color film substrate which are arranged in a form of paired boxes and comprises the following steps of: configuring a first planar transparent electrode in the color film substrate of the liquid crystal display panel, and configuring a second strip-shaped transparent electrode in the array substrate of the liquid crystal display panel, so as to form an edge electric field between the electrodes configured at the array substrate and the color film substrate through the first planar transparent electrode and the second strip transparent electrode; and controlling a display viewing angle of the liquid crystal display panel by controlling the formed edge electric field. According to the liquid crystal display viewing angle controlling method, the liquid crystal display panel and the liquid crystal display disclosed by the invention, the electrodes are respectively supplied in the color film substrate and the array substrate, and the controlling of a fringing field effect between the electrodes is utilized to enable a viewing angle of the liquid crystal display panel to be controllable, thus supplying the viewing angle controlling method for enabling the manufacturing process of the liquid crystal display panel to be simple.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to a liquid crystal display viewing angle control method, a liquid crystal display panel and a liquid crystal display. Background technique [0002] With the wide application of liquid crystal displays in life and work, people have higher and higher requirements for the viewing angle of liquid crystal displays. For example, for notebook computers used by individuals, when individuals use notebook computers in public places, they hope to have a smaller viewing angle to protect privacy. The display has a larger viewing angle so that it is convenient for multiple people to use. For example, a public computer in a bank service hall also needs a "public" mode that everyone enjoys and a "private" mode that prevents peeping. [0003] Based on this requirement, some display methods with controllable viewing angles have been proposed in the prior art, such as using multiple liquid crysta...
