Please continue A with reference to Fig. 3, below easy for narration, be the example narration only with pixel circuit 360.Need be on its panel during display frame when LCD, scan drive circuit 320 can be earlier by sweep trace X
3Send sweep signal to being coupled to sweep trace X
3The gate terminal of all TFT, in order to two source/drain electrode ends of these TFT of conducting.If this moment, the zone at pixel circuit 360 places was viewing areas, then control circuit 310 can send shift pulse Vshift to the shifting cache module, in order all transmission locks of conducting singly.When transmission lock 332 was switched on, its signal input part 35 can receive data-signal Vdata, and delivered to data line Y by its signal output part 37
3During this time, partial mode signal Vpm can control section in the mode circuit 340 all for example the on-off circuit of MOS transistor 43 close (Turn Off).When data-signal Vdata by data line Y
3When delivering to TFT 361, data-signal Vdata can be by its source/drain electrode end 47 conductings to source/drain electrode end 49, with to electric capacity 362 chargings, and makes pixel capacitors 363 shinny on picture.
And if the zone at pixel circuit 360 places is non-display areas, control circuit can stop to send shift pulse Vshift to data drive circuit 330, and changes with all switch conductions of MOS transistor 341 for example in the part mode signal Vpm control section mode activated circuit 340.When MOS transistor 341 conductings, can be with common electric voltage Vcom by data line Y
3Deliver to TFT 361, and common electric voltage Vcom can be by its source/drain electrode end 47 conductings to source/drain electrode end 49, and in this time, two terminal potentials of pixel capacitors 363 and electric capacity 362 equate, therefore electric capacity 362 can not be recharged, so pixel capacitors 363 can not produce light on picture.
Please refer to Fig. 4, be LCD internal circuit diagram according to another embodiment of the present invention.The different places of present embodiment and a last embodiment for not using the part display driver circuit 340 among Fig. 3 A for example, but are used the two ends that switching transistor is coupled to pixel capacitors instead.Below easy for narration, be example only with pixel circuit 450.Pixel circuit 450 can include TFT 441, electric capacity 442, pixel capacitors 443 and switching transistor 444.The two ends of the pixel capacitors 443 of two sources/drain electrode end cross-over connection of switching transistor 444 to the display panels, its two sources/drain electrode end is coupled to the two ends of pixel capacitors 443 respectively, and its gate terminal then receives partly mode signal Vpm and is used for whether conducting of determine switch transistor 444.If the zone at pixel circuit 450 places is the viewing area, then its method of work is identical with a last embodiment, does not repeat them here.And if the zone at pixel circuit 450 places is a non-display area, then control circuit 310 can stop to send shift pulse Vshift, partial mode signal Vpm makes the substantially short circuit of two ends of pixel capacitors 443 with 444 conductings of gauge tap transistor then, does not therefore have light on picture.
Though above proposition another kind makes the equipotential circuit in pixel capacitors two ends, be not must be all pixel capacitors all must couple a transistor circuit.Those skilled in the art can only couple transistor circuit with pixel capacitors partly according to the actual needs.
Please refer to Fig. 5, be display part display mode workflow diagram according to preferred embodiment of the present invention.Comprehensive above two embodiment, and after doing an arrangement, we can summarize partly display mode method of work of a display.At first, when display is worked, as described in step S502, judge whether the zone at each pixel circuit place is the viewing area under partial mode as described in the step S501.If the zone at pixel circuit place is the viewing area,, work as display such as the full display mode then as described in the step S504.But if the zone at pixel circuit place is a non-display area, then carry out step S503, the two ends equipotential of control pixel capacitors.
The present invention has proposed two kinds and has made the equipotential method in pixel capacitors two ends in Fig. 3 A and Fig. 4, put in order as followsly, at first please refer to Fig. 6, for making pixel capacitors two ends equipotential method flow diagram according to one of the present invention preferred embodiment.At first as described in the step S601, control circuit stops the data driving circuit is sent shift pulse.Step S602 is described for another example, controls a common electric voltage and delivers to pixel capacitors by the data line of display panels.At last as described in the step S603, pixel capacitors two ends equipotential.
Please refer to Fig. 7, be the method flow diagram that makes pixel capacitors two ends equipotential according to another preferred embodiment of the present invention.Another kind provided by the invention makes the method for pixel capacitors two ends equipotential, is earlier as described in the step S701, and control circuit stops the data driving circuit is sent data-signal.At this moment, as described in step S702, send into a partial mode signal by the partial mode signal end, control pixel capacitors two ends are equivalent to short circuit, and as described in the step S703, the pixel capacitors two ends can be regarded short circuit as then.
In sum, when the present invention works in the part display mode when LCD, in its non-display area, directly make the two ends equipotential of pixel capacitors, do complicated running, therefore can reduce the consumption of power greatly and needn't export shift pulse again.
Though the present invention with a preferred embodiment openly as above; right its is not in order to limit the present invention; any person of ordinary skill in the field; without departing from the spirit and scope of the invention; when can doing a little change and modification, so the present invention's protection domain is as the criterion when looking the claim person of defining.
