Embodiment 1

[0028] In this embodiment, the thickness of the liquid crystal layer of the VA liquid crystal display is 1.5 μm, and the driver uses a power supply with a driving frequency of 150 Hz to drive the VA liquid crystal display. From the three aspects of response time, viewing angle and contrast, this embodiment is compared with the current VA liquid crystal display device, and the specific comparison data are as follows:

[0029] Contrast Example 1 Current VA liquid crystal display device Response time 33.1 65～91 Viewing angle no dead zone May have blind spots contrast 270 154～180

Embodiment 2

[0031] In this embodiment, the thickness of the liquid crystal layer of the VA liquid crystal display is 2.0 μm, and the driver uses a power supply with a driving frequency of 220 Hz to drive the VA liquid crystal display. From the three aspects of response time, viewing angle and contrast, this embodiment is compared with the current VA liquid crystal display device, and the specific comparison data are as follows:

[0032] Contrast Example 1 Current VA liquid crystal display device Response time 32.2 65～91 Viewing angle no dead zone May have blind spots contrast 282 154～180

Embodiment 3

[0034] In this embodiment, the thickness of the liquid crystal layer of the VA liquid crystal display is 2.5 μm, and the driver uses a power supply with a driving frequency of 400 Hz to drive the VA liquid crystal display. From the three aspects of response time, viewing angle and contrast, this embodiment is compared with the current VA liquid crystal display device, and the specific comparison data are as follows:

[0035] Contrast Example 1 Current VA liquid crystal display device Response time 35 65～91 Viewing angle no dead zone May have blind spots contrast 281 154～180

[0036] As can be seen from the foregoing embodiments, the present invention reduces the thickness of the liquid crystal layer in the VA liquid crystal display to 1.5 to 2.5 μm, and increases the driving frequency of the power supply for driving the VA liquid crystal display provided by the driver to more than 150 Hz, which can increase the VA The response speed of ...

Abstract

The invention discloses a VA liquid crystal display device and method. The method comprises the following steps of reducing the thickness of a liquid crystal layer in a VA liquid crystal display; increasing the driving frequency of a power supply provided by a driver, wherein the driver uses the power supply for driving the VA liquid crystal display. The thickness of the liquid crystal layer in the VA liquid crystal display is reduced, the driving frequency of the power supply provided by the driver is improved, and the driver adopts the power supply for driving the VA liquid crystal display, so that the response speed of the VA liquid crystal display device can be accelerated. Meanwhile, the visible angle and the contrast ratio of the VA liquid crystal display device can be further increased.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a VA liquid crystal display device and method. Background technique [0002] With the continuous development of liquid crystal display technology, in order to increase the viewing angle and contrast ratio of liquid crystal display, VA (Vertical Alignment, vertical alignment) liquid crystal display device emerges as the times require. However, current VA liquid crystal display devices have a disadvantage of slow response speed. Contents of the invention [0003] In order to solve the above problems, the present invention provides a VA liquid crystal display device and method to solve the problem of slow response speed of the current VA liquid crystal display device. [0004] According to one aspect of the present invention, there is provided a vertical alignment VA liquid crystal display device, comprising a VA liquid crystal display and a driver, the VA liquid crystal dis...
