Problems solved by technology
[0005] The present invention provides a line scan control method of a display control chip and a storage medium, aiming at solving the problem that the line erasure operation of each scanning line in a dynamic display screen in the traditional technology can only be started once, and the erasure of the display screen cannot be performed. If the function is adjusted arbitrarily, the effect of the screen disappearing is not good, and there is still a serious smear phenomenon on the screen, which further reduces the display effect of the screen, and the viewer's visual experience is not good.

Embodiment Construction
[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0040] It should be noted that in the traditional technology, technicians usually use a display control chip to cyclically scan the scanning lines of the display screen, and then drive the scanning lines in multiple display screens to be turned on cyclically, and the display screen can display a complete image / Video information; Exemplary, figure 1 A schematic structural diagram of the display control chip 10 provided by the embodiment of the present invention is shown, as shown in figure 1 As shown, the display control chip 10 includes: a shift register 101, a logic controller 102, a plurality o...

The invention belongs to the technical field of display screen control, and provides a line scan control method and a storage medium of a display control chip; the display control chip includes: a shift register, a logic controller, a plurality of switch units and a plurality of erasure units; The row scan control method includes: outputting the write state operation signal to the display control chip in time sequence every preset time, and setting the internal parameters of the display control chip through the write state operation signal time sequence, so that all The display control chip performs multiple row line erasure operations and adjusts the erasure voltage of the erasure unit during the row scanning process; wherein, the timing of the write state operation signal includes: write state start instruction, write state enable instruction And write state end instruction. The present invention solves the problems of incomplete scanning line elimination of the display screen in the traditional technology, resulting in poor picture quality of the display screen and poor visual experience.
Description
technical field [0001] The invention belongs to the technical field of display screen control, and in particular relates to a row scan control method of a display control chip and a storage medium. Background technique [0002] With the rapid development of modern industrial technology, the display screen has become an indispensable electronic component in the current industrial production process. Due to the simple production of the display screen and low control cost, the display screen has been widely used in various industrial technology fields. According to the line scanning mode of the display screen in the traditional technology, the display screen can be divided into a dynamic display screen and a static display screen, wherein all the scanning lines in the static display screen are turned on at the same time, and the corresponding LED (Light Emitting Diode (light-emitting diode) is controlled by different display control chips, so it is necessary to use multiple dis...
