Description
Technical field
The invention relates to a kind of switching component structure of active array-type display, refer to the switching component structure of the active matrix formula display of a kind of drain electrode that reduces changeover module gate line and changeover module and the coupling effect between source electrode especially.
Background technology
Active array-type display mainly is to utilize the thin-film transistor that is rectangular arrangement, cooperates electronic building bricks such as suitable electric capacity, switching pad to drive liquid crystal pixel, enriches beautiful image with generation.In recent years, for guaranteeing the display quality of active array-type display, when making active array-type display, can make a testing circuit in the lump, wherein an end of testing circuit is electrically connected to pixel gates line and pixel data line, and the other end that sees through testing circuit is imported a detection signal, detects with image element circuit, pixel gates line and pixel data line to display.
Though testing circuit can provide the function that detects display picture element circuit, but because testing circuit includes a short bar (shorting bar), directly together with all picture element scan lines and all pixel data line short circuits, therefore after test is finished, must utilize the laser mode to cut off with the short-circuit condition between each picture element scan line and each pixel data line, or the side that utilizes the worn display panels of edging mode is to remove the short bar between each picture element scan line and each pixel data line, the function otherwise display can't be brought into normal play.Increase cost and the shortcoming that reduces production capacity yet aforesaid way all has, thunderous shooting method is time-consuming and increase cost, and worn mode more can't be applicable to the situation of biliquid LCD panel (dualdisplay panel) shared data line except that increasing cost.
Therefore, developed now the operation and the method for detected state that utilize the changeover module switching display, that is be that switching assembly, for example a thin-film transistor is set in addition between each picture element scan line or each pixel data line and short bar.When detecting display, changeover module is to be conducting state, make detection signal be sent to each picture element scan line and each pixel data line by changeover module via short bar, to detect, and when display is desired normal the demonstration, changeover module is to be off state, makes between each scan line and each data wire to keep electrically separating.
Please refer to Fig. 1, Fig. 1 is for looking schematic diagram on the switching component structure of known active array-type display.As shown in Figure 1, known switching component structure 10 includes a substrate 11, changeover module gate line 12, a plurality of first changeover module 14a and a plurality of second a changeover module 14b along first direction X setting.The first changeover module 14a and the second changeover module 14b are gate electrode with changeover module gate line 12 all.The first changeover module 14a and the second changeover module 14b include a drain electrode 20a, 20b and one source pole electrode 22a, 22b all respectively.Wherein drain electrode 20a, the 20b of the first changeover module 14a and the second changeover module 14b are connected to the pixel gates line or the pixel data line (figure does not show) of viewing area all respectively along the end of second direction Y, and source electrode 22a, the 22b of the first changeover module 14a and the second changeover module 14b then are connected to one first short bar 24a and one second short bar 24b along the other end of second direction Y respectively.In addition, changeover module gate line 12 is to be strip, and it is identical with the overlap channel width 26 of the length of part and the first changeover module 14a and the second changeover module 14b of source electrode 22a, 22b and drain electrode 20a, 20b.
Generally speaking, the first changeover module 14a and the second changeover module 14b are the sides that all is arranged at display, in order to make detection signal can be sent to each pixel to detect, the detection signal of being imported need have the thin-film transistor that enough magnitudes of current could drive each pixel, and is accomplished detection.In order to make the magnitude of current that inputs in the display enough big, the channel width of changeover module also must increase, and to improve the magnitude of current restriction of changeover module, makes detection signal have enough magnitudes of current and is sent to each pixel.Yet, in above-mentioned known switching construction, the channel width 26 that increases by the first changeover module 14a and the second changeover module 14b promptly represents to increase the width of changeover module gate line 12, but because the increase of changeover module gate line 12 width also makes changeover module gate line 12 and the overlapping area of drain electrode 20a, 20b and source electrode 22a, 22b increase, and the coupling capacitance between changeover module gate line 12 and drain electrode 20a, 20b and source electrode 22a, 22b is increased, and produce coupling effect.That is, in importing detection signal to the first short bar 24a and not importing under the situation of detection signal to the second short bar 24b, detection signal is in through the source electrode 22a of the first changeover module 14a and drain electrode 20a the time, detection signal can be passed to the second changeover module 14b by coupling capacitance and via changeover module gate line 12, and then can receive rub-out signal in the second short bar 24b that the second changeover module 14b is connected.Therefore, the coupling effect between changeover module gate line 12 and drain electrode 20a, 20b and source electrode 22a, 22b can influence the testing result at different pixels data wire or pixel gates line.
In addition, at present in order to make undersized display, all changeover module and short bar are designed to be arranged at the same side of display, therefore shortened the distance between each changeover module, yet, the reduction of this distance will make between each changeover module can produce coupling effect, and the testing result that also can make the mistake.
From the above, improve the real target of needing effort for industry badly of coupling effect of coupling effect between gate line and drain electrode and source electrode and each changeover module.
