Problems solved by technology
In particular, when the display device displays a static picture, due to the difference in the above-mentioned processing procedures, the modified display parameters of two adjacent frames in the modified display signal may be very different from the original display parameters of two adjacent frames in the original display signal. If there is no difference or little difference between the display parameters, the discrepancy will be reflected on the final display screen, manifested as the jitter of the static screen, resulting in poor display effect

Embodiment Construction
[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.
[0035] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) in the embodiment of the present application, the directional indications are only used to explain the position in a certain posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0036] In addition, if there are descriptions involving "first", "second", etc....

The application discloses a display driving method, a display driving device and a display device. The display driving method includes the following steps: obtaining the original display parameters oftwo adjacent frames before processing and the corrected display parameters of the two adjacent frames after processing; comparing the absolute value of the difference between the original display parameters of the two adjacent frames at the same position with a first preset threshold; if the absolute value of the difference between the original display parameters of the two adjacent frames at thesame position is smaller than or equal to the first preset threshold, comparing the absolute value of the difference between the corrected display parameters of the two adjacent frames at the corresponding position with a second preset threshold; and if the absolute value of the difference between the corrected display parameters of the two adjacent frames at the corresponding position is greaterthan the second preset threshold, modifying the color adjustment coefficient to reduce the change of the corrected display parameter of the same frame at the same position relative to the original display parameter. The technical scheme of the application can improve the display effect of a static picture.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a display driving method, a display driving device and a display device. Background technique [0002] In the display device, in order to improve the display effect, the original display signal directly received from the display signal source is usually processed to a certain extent, such as optimizing color, gamma adjustment, reducing jitter, etc., and the corrected display signal obtained after processing Relative to the original display signal often has a large change. In particular, when the display device displays a static picture, due to the difference in the above-mentioned processing procedures, the modified display parameters of two adjacent frames in the modified display signal may be very different from the original display parameters of two adjacent frames in the original display signal. If there is no difference or little difference between the display pa...
