Embodiment Construction

[0053] In order to make the above-mentioned purpose, features and advantages of the present application more obvious and understandable, the specific implementation manners of the present application will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the application. However, the present application can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific implementation disclosed below.

[0054] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" an...

Abstract

The present application provides a driving method of a display panel, including first acquiring a first common voltage; and then determining a preset threshold value according to the first common voltage; at last, that second common voltage is output accord to the first common voltage and the preset threshold value. The present application also provides a driving device of a display panel. A computer device is also provided. As with this method of that present application, only one common voltage need to be adjusted and the other common voltage automatically follow based on the preset threshold, i. e., the purpose of fixing the voltage difference is achieved. At that same time, the present application can also improve work efficiency.

Description

technical field [0001] The present application relates to the technical field of liquid crystal display, in particular to a driving method, device and computer equipment of a display panel. Background technique [0002] The viewing angle of the liquid crystal display panel is not large enough. At present, it is more popular to divide a pixel into a main pixel (main) and a sub-pixel (sub), and release the voltage of the sub-pixel to a lower level to ensure the brightness performance of the side viewing angle. . For the discharge scheme of sub-pixels, a design of dual common electrodes (CF-VCOM, Array-VCOM) has been proposed recently. By releasing the sub-pixel voltage of the liquid crystal to the Array-VCOM voltage, the voltage difference between the two ends of the liquid crystal of the sub-pixel is the difference between Array-VCOM and CF-VCOM. [0003] At present, these two VCOM voltages are provided by independent power supply, and are not linked with each other, so the...
