Problems solved by technology

[0006] However, the above method not only requires an additional circuit to generate the modulation signal of the storage capacitor, but also needs to increase panel wiring to transmit the modulation signal of the storage capacitor, which will reduce the aperture ratio of the LCD panel.

Embodiment Construction

[0035] Certain terms are used in the specification and subsequent claims to refer to particular components. Those of ordinary skill in the art will appreciate that manufacturers may refer to the same component by different terms. This description and subsequent patent applications do not use the difference in name as a way to distinguish components, but use the difference in function of components as a basis for distinction. The "comprising" mentioned throughout the specification and subsequent claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "electrical connection" here includes any direct and indirect electrical connection means. Therefore, if it is described in the text that a first device is electrically connected to a second device, it means that the first device can be directly connected to the second device, or indirectly connected to the second device through other devices or connection means.

Abstract

The invention provides a liquid crystal display device for improving the phenomenon of color cast; storage capacitors of two subpixels in a pixel are in electric connection with the next scanning line and the one after the next respectively; through a driving signal of the scanning line, the voltage of the storage capacitor is modulated to allow two subpixels to have different driving voltages respectively, thereby improving the problem of the color cast of a squint angle.

Description

technical field [0001] The present invention refers to a liquid crystal display device for improving the phenomenon of color shift, especially a liquid crystal display device that uses the driving signal of the scanning line to adjust the driving voltage of the sub-pixels to improve the problem of squinted color shift. Background technique [0002] Liquid crystal displays have been widely used in information products such as notebook computers, personal computer monitors, and personal digital assistants due to their thin and light appearance, low power consumption, and no radiation pollution, and have gradually replaced traditional cathode ray tube TVs. , becoming the mainstream of home TV products. [0003] Compared with traditional cathode ray tube displays, liquid crystal displays are prone to differences in brightness and contrast due to different viewing angles of users, and even grayscale inversion phenomenon at large viewing angles. Therefore, the industry has develo...
