Embodiment
In order to make purpose of the present invention, technical scheme and beneficial effect clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The block schematic diagram of the over-driving device that Fig. 2 provides for one embodiment of the invention.With reference to Fig. 2, over-driving device 200 comprises: storage unit 210, position units 220 and over-drive unit 230.Wherein, over-driving device 200 is in order to produce the picture IMG_OD that overdrives, to comprise the display panel of a plurality of viewing areas with driving.For convenience of description, the synoptic diagram of the display panel that Fig. 3 provides for one embodiment of the invention, wherein display panel 300 comprises: 9 viewing area AR1～AR9, just N=9.Though Fig. 3 has enumerated the enforcement kenel of display panel, it is not in order to qualification the present invention, and the cited display panel 300 of the following Fig. 3 that will arrange in pairs or groups illustrates the running of over-driving device 200.
In overall operation, storage unit 210 is in order to storing the present picture IMG_N that is received, and can export the previous picture IMG_N-1 that has been stored in the storage unit 210.Therefore, for over-drive unit 230, it can receive present picture IMG_N and previous picture IMG_N-1 simultaneously.On the other hand, position units 220 produces location of pixels information IM2 in order to the display control signal SC2 with reference to present picture IMG_N.Wherein, the display control signal SC2 of described present picture IMG_N for example is the combination of a vertical synchronizing signal, a horizontal-drive signal and a data enable signal.In addition, store a plurality of tables of overdriving in the over-drive unit 230, and described overdrive table respectively with display panel 300 in the part viewing area corresponding mutually, with foundation different liquid crystal reaction time and setting up.
For instance, be example with Fig. 3, if the interior reservoir of over-drive unit 230 has 3 tables of overdriving, wherein said 3 tables of overdriving are corresponding mutually with viewing area AR1, AR5, AR9 respectively.And know that according to the type of drive of the P-SCAN of display panel 300, be positioned at the liquid crystal of top more of display panel 300, its required reaction time is longer, the GTG value of overdriving that just liquid crystal is required is less.Relatively, be positioned at the liquid crystal of below more of display panel 300, its required reaction time is shorter, and the GTG value of overdriving that just liquid crystal is required is bigger.Therefore, under with reference to the situation of setting up the table of overdriving with viewing area AR1, AR5, AR9 corresponding liquid crystal reaction time, will store the tables of setting up according to the different liquid crystal reaction time of overdriving in the over-drive unit 230.
In addition, over-drive unit 230 is differentiated a plurality of pixel gray level values of present picture IMG_N and the corresponding relation of described a plurality of viewing areas with reference to location of pixels information IM2, from described a plurality of tables of overdriving, to select the pairing separately particular table group of these pixel gray level values, and produce the picture IMG_OD that overdrives by inquiring about the pairing separately particular table of these pixel gray level values group.In other words, over-drive unit 230 is with reference to the activation point of each pixel gray level value corresponding to display panel, respectively each pixel gray level value is changed and choose the different tables of overdriving.Thereby over-drive unit 230 can be adjusted each pixel gray level value in response to the required liquid crystal reaction time of different viewing areas.Relatively, the picture IMG_OD that overdrives that over-drive unit 230 is produced can avoid the liquid crystal transition to cross strong or the disappearance of liquid crystal transition deficiency, and then improve the quality of the image of display panel.
Further, as shown in Figure 2, over-drive unit 230 comprises a reservoir 231, a selector switch 232 and a data operator 233.Reservoir is in order to store a plurality of table TB21～TB24 that overdrive.Selector switch 232 is differentiated the pairing separately viewing area of a plurality of pixel gray level values among the present picture IMG N in order to foundation location of pixels information IM2, and with reference to the pairing separately viewing area of these pixel gray level values, and from a plurality of tables of overdriving, pick out the pairing separately particular table of these pixel gray level values group.
For instance, be example with Fig. 3, if reservoir 231 only comprise 3 overdrive the table TB21～TB23, and described overdrive the table TB21～TB23 corresponding mutually with viewing area AR1, AR5, AR9 respectively.When the pixel gray level value of changing when over-drive unit 230 was corresponding viewing area AR2, selector switch 232 will be from the table TB21～TB23 that overdrives, and picked out corresponding to overdriving of viewing area AR1 and AR5 and showed TB21 and TB22 is used as particular table group.Similarly, when if the pixel gray level value that over-drive unit 230 is being changed is corresponding viewing area AR6, selector switch 232 will be from the table TB21～TB23 that overdrives, and picks out corresponding to overdriving of viewing area AR5 and AR9 and shows TB22 and TB23 is used as particular table group.In other words, selector switch 232 is that reference pixels GTG value corresponding display is picked out two tables of overdriving, wherein the two table pairing viewing areas of neighborhood pixels GTG value, pairing two viewing area of overdriving.
On the other hand, data operator 233 can be with reference to present picture IMG_N and the particular table of picture IMG_N-1 inquiry before group, to obtain first over-drive value and second over-drive value.For instance, data operator 233 can capture the pixel gray level value among present picture IMG_N and the previous picture IMG_N-1 one by one, and inquires about the table of overdriving of two in the particular table group with reference to the pixel gray level value that is captured.Therefore, if 8 of the resolution of picture, two tables of being inquired about of overdriving are table 1 and table 2, and two pixel gray level values that data operator 233 is taken out from present picture IMG_N and previous picture IMG_N-1 are 128 and 32 o'clock, then with reference to table 1 and table 2, data operator 233 can be overdrived from two and be captured first over-drive value { 152} and the second over-drive value { 186} the table.
