Description
Technical field
The invention relates to a kind of video data compensation method and related LCD system, refer to the dynamic data compensation method and the related LCD system of a kind of touching moire (MURA) especially.
Background technology
(liquid crystaI display is a kind of flat-panel screens that is widely used most at present LCD) to liquid crystal display, has that external form is frivolous, features such as power saving and radiationless pollution.The principle of work of liquid crystal display is the ordered state that the voltage difference that utilize to change the liquid crystal layer two ends changes the liquid crystal molecule in the liquid crystal layer, uses the light transmission that changes liquid crystal layer and shows different images.In the various electronic products that comprise liquid crystal display, such as electronic products such as multimedia player, mobile phone or PDA(Personal Digital Assistant), the function of utilizing liquid crystal display to carry out the touching input gradually becomes popular, also be touch screen application more and more widely.Touch screen is based on resistance-type touching screen and capacitor-type touch screen.Resistance-type touching screen is that the capacitor-type touch screen comprises sense capacitance usually with voltage drop location touch position, according to the capacitance variations corresponding to the sense capacitance of touch points, orients touch position through signal Processing.
Yet when LCD screen was touched, the liquid crystal molecule in the liquid crystal layer can be squeezed and cause chaotic ordered state; After the touching, chaotic ordered state can't disappear immediately, need just can recover the original alignment state gradually after after a while, and this phenomenon is so-called moire (MURA) effect.Please refer to Fig. 1, the second signal state 120 of Liquid Crystal Molecules Alignment state, the 3rd signal state 130 of touching back Liquid Crystal Molecules Alignment state when Fig. 1 is the first signal state 110, the touching of former liquid crystal molecules align state when illustrating LCD screen 100 and never touching, and the 4th signal state 140 that recovers former liquid crystal molecules align state.As shown in Figure 1, LCD screen 100 comprises upper substrate 111, infrabasal plate 118 and liquid crystal molecule 115.
The first signal state 110 shows when LCD screen 100 is not touched, the former liquid crystal molecules align state of rule, the second signal state 120 shows when LCD screen 100 is touched, upper substrate 111 is because of being touched micro-deformation by external force, the ordered state that causes the interior liquid crystal molecule 115 of liquid crystal layer to be squeezed and cause confusion, the 3rd signal state 130 shows after LCD screen 100 is touched, though upper substrate 111 has restored to the original state, liquid crystal molecule 115 in the liquid crystal layer is because of inertia effect, still remain on chaotic ordered state, it is moire effect, the 4th signal state 140 shows that after one period duration, the liquid crystal molecule 115 in the liquid crystal layer just reverts to the former liquid crystal molecules align state of rule.Usually, moire effect can cause the regional irregular demonstration situation of LCD screen, causes uncomfortable visual experience, so the duration of moire effect is short more good more.
