Problems solved by technology

[0005] Fall time reduction is much more complex and less feasible to implement than rise time reduction
On the one hand, while reducing the falling time by changing the liquid crystal material, it is likely to cause a decline in other characteristics of the display panel
For example, resulting in a narrowing of the operating temperature range
On the other hand, it is also difficult to improve the fall time by improving the design of the liquid crystal cell

Abstract

The invention discloses a homeotropic alignment type liquid crystal display device and a driving method thereof. Two horizontal electrodes are added on the basis of an existing structure. Negative liquid crystal molecules are made to rotate to the direction of a light-transmitting shaft of a polaroid in the horizontal direction through a generated horizontal electric field, the process that the liquid crystal display device is switched to a dark state from a bright state is accelerated, and fall time is effectively shortened. High-speed response speed is high, and the better display effect is achieved when a high-speed dynamic frame is displayed.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a vertical alignment type liquid crystal display device, and also relates to a method for driving the vertical alignment type liquid crystal display device. Background technique [0002] In recent years, active TFT-LCD display devices have been developed rapidly and widely used. There are many indicators to evaluate the pros and cons of TFT-LCD display products, such as resolution, contrast, color gamut, response time and so on. Wherein, the response time represents the time required for the brightness switching process of the liquid crystal panel, and is an important parameter of the dynamic response capability of the liquid crystal. Generally speaking, the faster the response time, the higher the maximum screen refresh rate that the display panel can achieve, so the degree of smearing is smaller, and the displayed dynamic screen with high-speed motion is clearer.
