Embodiment Construction
[0045] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0046] The common electrode voltage is a voltage applied to the common electrode of the liquid crystal display, which is determined by the characteristics of the liquid crystal and the working principle of the liquid crystal module. There is a positive and negative deflection voltage in the LCD drive circuit, and the common electrode voltage needs to be set at the center point of the positive and negative deflection voltage. By adjusting the value of the common electrode...

The invention discloses a display screen common voltage programming method and a device, and a computer readable storage medium. The display screen common voltage programming method comprises the following steps of acquiring a first optimum common voltage value for display screen preheating in first set time, wherein the first optimum common voltage value is the common voltage value correspondingto a minimum scintillation value in the first set time, and the scintillation value expresses the scintillation degree of a display screen; using a sum of the first optimum common voltage value and apreset offset range, determining a common voltage programming range; and acquiring any one common voltage value in the common voltage programming range and programming so that the display frame of thedisplay screen satisfies a scintillation standard. In the invention, the scintillation problem of an asymmetric electrode structure display screen is solved, the scintillation of the display screen accords with the scintillation standard, production efficiency is increased and production cost is reduced.
Description
technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular, to a method, device and computer-readable storage medium for programming a common voltage of a display screen. Background technique [0002] Along with the large screen of the liquid crystal display, the same liquid crystal display includes a plurality of small screens. Usually, the common voltage value is set by software initialization, and the common voltage value of all small screens is the same. However, due to the influence of impedance differences and other factors, the optimal common voltage value of each small screen is not the same. The farther the optimal common voltage value deviates from the initial set common voltage value, the smaller the screen will flicker. [0003] At present, the optimal common voltage value can be individually programmed for each small screen through one-time programming, so as to solve the flickering problem cause...
