Embodiment Construction
[0039] A data compensation method and device for a liquid crystal display provided by the present invention will be described in more detail below with reference to the accompanying drawings and embodiments.
[0040] Such as figure 1 As shown, the embodiment of the present invention provides a data compensation method for a liquid crystal display, and its specific implementation is as follows:
[0041] Step 110, when starting up, determine the timing duration ΔT' from the last shutdown, and determine the mura data compensation table a called when the last shutdown m ;
[0042] Step 120, according to the time T required for the preset mura stabilization, the mura data compensation table corresponding to the preset different time periods, and the determined above-mentioned ΔT', the above-mentioned mura data compensation table a m , to determine the mura data compensation table to be called when starting up this time;
[0043] Wherein, the preset stabilization time T required ...

The embodiment of the invention discloses a data compensation method and a data compensation device for a liquid crystal display screen. The method comprises the following steps of during a start-on process, determining timing duration delta T' from the last shutdown moment, and determining a frame display unevenness mura data compensation table am called at the last shutdown moment; determining a mura data compensation table called at this-time start-on moment according to a preset time T needed for mura stabilization, a preset mura data compensation table corresponding to different time intervals as well as the determined delta T' and the determined mura data compensation table am; and starting performing data compensation from the determined mura data compensation table called at this-time start-on moment. Since different mura data compensation tables are configured for different time intervals, after the data compensation device is started on, a suitable initiative data compensation table is determined in combination with the time needed for mura stabilization, the timing start time from the last shutdown moment and the data compensation table called at the shutdown moment, and the compensation effect is better.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a data compensation method and device for a liquid crystal display. Background technique [0002] At present, it takes a period of time for the liquid crystal display to enter a stable display state from being turned on to a stable temperature. During this period of time, as the temperature gradually rises to a stable state, correspondingly, the picture display in the liquid crystal display is uneven (mura) It is a process of changing from heavy to light and finally stabilized. For the mura problem, in the prior art, a mura data compensation table is generally called to compensate after the power is turned on. After shutting down, the temperature will gradually drop, and the mura of the LCD screen itself will slowly return to the initial state. If the power is turned on again before returning to the initial state, at this time, calling the above mura data compensation table will...
