Description
Technical field
The present invention relates to a kind of method that solves display delay, refer to a kind of order of adjusting the pixel capacitance unlatching of utilizing especially, obtain the method for the improvement of LCD picture.
Background technology
The development of electronic product is in recent decades thing only, but its speed of development is placed oneself above on the other industries, especially the audio-visual aspect of computing machine related peripheral and audiovisual product, more because the demand of people's work or leisure aspect, further significant progress is more arranged, and the release of new product is constantly arranged.With regard to such as display (Display), traditional display is constituted by a conventional picture tube, and it has following shortcoming:
1. traditional monitor is an on-plane surface, can produce the phenomenon of image distortion on the picture when therefore watching.
2. kinescope is bigger in the consumed power of concerned power, and it is bigger that meaning is its power consumption, can produce the high temperature and the hot phenomenon of display simultaneously.
3. the volume that is subject to conventional picture tube is excessive, makes the volume of display to reduce, and produces locating of inconvenience in the use sometimes because of usage space is too little.
Because of traditional monitor has above-mentioned defective, so there is manufacturer to drop into the follow-on display of exploitation, and comprising LCD and plasma display etc. are arranged, but it seems at present, the manufacturing technology of LCD is comparatively ripe, and its price has been reduced near the conventional picture tube display, and this LCD plurality of advantages of having low radiation, low power consumption, small size and watching the visual angle more greatly, thus widely generally the user like.
LCD is applied to the display (as: mobile phone, digital camera) of graphoscope, LCD TV and 3C electric equipment products etc. mostly at present, and the aspect of application is considerably extensive.See also Figure 1A, shown in Figure 1B, the display frame of conventional liquid crystal and pixel capacitance open operation synoptic diagram, for display frame being divided into a plurality of zones, the opening ways of the pixel capacitance in these a plurality of zones, for leftmost side pixel Hs (1) that certainly should the zone as the starting point of opening, carry out open operation (open from left the rightmost side in the zone of also can serving as reasons) in regular turn to the right, up to be opened into all pixel capacitances of rightmost side pixel Hs (N) all be unlocked finish after, eliminate the operation of pixel (pixel capacitance discharge) again, so go round and begin again, to form the operation that all pictures show, but utilize the shown picture of this conventional liquid crystal, often be divided the back segment in a plurality of zones in this, duration of charging deficiency because of its pixel capacitance, just the phenomenon that presents a kind of color desalination, for example: the zone that should show black, but show the situation of grey, the zone that so just presents several color desalinations on the picture, and then influence the correctness that picture shows, therefore the present invention is just for improving this phenomenon, utilize and adjust the order that pixel capacitance is opened, obtain the improvement of LCD picture.
