Embodiment Construction
[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0048] The terms 'first', 'second', etc. in the present invention may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first control could be termed a second control, and, similarly, a second control could be termed a first control, without departing from the scope of the present invention. Both the first contro...

The invention discloses a driving device and a display device. After a signal obtaining unit obtains data signals of an image, a display searching unit obtains a first driving voltage signal and a second driving voltage signal which is corresponding to the data signals; a first generation unit generates a first quasi-driving voltage signal from the first driving voltage signal and the second driving voltage signal according to a first preset generation rule and generates a second quasi-driving voltage signal from the first driving voltage signal and the second driving voltage signal accordingto a second preset generation rule. A factor calculation unit calculates a high frequency factor corresponding to each pixel in the data signals according to a preset calculation rule. A second generation unit generates a driving voltage signal according to the high frequency factor, the first quasi-driving voltage signal and the second quasi-driving voltage signal. The driving unit drives a display panel to display an image according to the driving voltage signal. The driving device and the display device can improve a visual angle of the display device and a contrast ratio of the image in alarge visual angle, and greatly improve a color cast of the image in the large visual angle.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a driving device and a display device. Background technique [0002] With the development of the liquid crystal display field, higher image quality has become the main indicator of major display manufacturers. As an important indicator of image quality, the viewing angle has become an important parameter of a VA (Vertical Alignment, vertical alignment technology) liquid crystal display device. However, in the existing VA-type liquid crystal display device, the curve of the transmittance and the driving voltage will be seriously shifted at a large viewing angle, which leads to a decrease in the contrast of the picture at a large viewing angle, and the problem of color shift is prone to occur. Contents of the invention [0003] The invention provides a driving device and a display device to improve the picture contrast of the display device at a large viewing angle and improve ...
