A low-temperature fast steady-state display method for a high-brightness liquid crystal display screen in a starting stage

Abstract

This invention belongs to the field of fast-response liquid crystal technology and relates to a low-temperature fast steady-state display method for a high-brightness liquid crystal display during the startup phase. During the low-temperature startup phase of the fast-response liquid crystal display, the touch coordinate sequence is filtered to calculate the predicted landing point area for the next moment. The current viscosity coefficient is obtained by querying a mapping table based on the current temperature value, and a first overdrive voltage value is calculated by combining it with the target grayscale difference. The first overdrive voltage is applied to the sub-pixels of the predicted landing point area, and a second base sustaining voltage is applied to the unpredicted areas. When the predicted landing point area reaches the target grayscale, the first overdrive voltage is applied as a traveling wave voltage, gradually extending to the unpredicted areas in a spatially adjacent order, until the entire screen voltage converges to the steady-state operating voltage. This invention staggers the application of the overdrive voltage in both space and time, reducing the instantaneous current load of the power supply during the low-temperature startup phase and avoiding system power-off reset caused by overcurrent protection.
