Certainly, the layout kenel of electric field shielding layer 370 also can be shown in Fig. 6 C, the strip pattern 372 of electric field shielding layer 370 is divided into a plurality of block B1, B2 with sub-pixel 252, each block B1, B2 comprise three row pixel P1, P2, P3 respectively, wherein nine row sub-pixels 252 for example have identical polarity in same block, and its with adjacent block in other three row pixel P1, P2, P3 have different polarity.Therefore, the present invention is not in order to limit the layout kenel of electric field shielding layer.
Certainly, the bearing of trend of strip pattern 372 also can be parallel to the bearing of trend of data line 256, and between part sub-pixel 252 adjacent one another are.Fig. 7 A to Fig. 7 C is respectively the touch-control liquid crystal display panel of Fig. 5 at another kind of signal condition and the electric field shielding layout layer synoptic diagram of a picture frame in the time.Shown in Fig. 7 A to Fig. 7 C, in the present embodiment, the bearing of trend of strip pattern 372 can be the bearing of trend that is parallel to data line 256, and between part sub-pixel 252 adjacent one another are.In other words, the type of drive of touch-control liquid crystal display panel in the present embodiment is to be example to go inversion driving, and the strip pattern 372 of electric field shielding layer 370 then is arranged on different ranks along line direction and has between the sub-pixel of opposed polarity.
As aforementioned, on behalf of the strip pattern of electric field shielding layer, Fig. 7 A and Fig. 7 B respectively the sub-pixel on the pel array is divided into the not kenel of the block of commensurate, make the sub-pixel 252 in same block have identical polar, but have different polarity with sub-pixel 252 in the adjacent block.In brief, each block B1, B2 among Fig. 7 A, B3 comprise delegation's sub-pixel 252 respectively, and each block B1, B2 among Fig. 7 B then comprise triplex row sub-pixel 252 respectively, and it is described that other design considers to analogize previous embodiment.Therefore, the present invention is not in order to limit the layout kenel of electric field shielding layer.
The present invention also provides a kind of display panels, and the element of touch-control sensing function is not set in display panels, and the electric field shielding layer still is set.With Fig. 2 A, Fig. 2 B is the example explanation, and display panels comprises active component array base board 210, subtend substrate 220 and liquid crystal layer 230, and Support, gap 204 and viewing area 206 only are set, but touch-control sensing district 202 is not set.In the present embodiment, shown in Fig. 2 A, subtend substrate 220 has a common electrode 222, and liquid crystal layer 230 is disposed between active component array base board 210 and the subtend substrate 220.Active component array base board 210 comprises first substrate 240, pel array 250 and electric field shielding layer 270, and wherein electric field shielding layer 270 comprises a pattern.Therefore other parts repeat no more as described in the embodiment of front.After this display panels is subjected to pressed by external force, electric field shielding layer 270 still can cover the influence of grid field effect for liquid crystal molecule, the shielding liquid crystal molecule is subjected to the electric field effects between adjacent subpixels 252 and the common electrode 222, help the liquid crystal molecule at the place of being pressed to be returned to ordered state originally fast, can avoid pushing moire and residue in display panels.
In sum, because touch-control liquid crystal display panel of the present invention and display panels employing electric field shielding layer directly shield the electric field between the sub-pixel adjacent one another are, reduce the electric field effects that liquid crystal molecule is subjected to adjacent subpixels, help touch-control liquid crystal display panel after suffering pressed by external force, can reply fast and be not easy to push the residual problem of moire (Press Mura).
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
