2. The Related Arts
With the increasing progress of the liquid crystal display technology, liquid crystal displaying devices, such as light emitting diode panels, which serve as a display component, has been widely used in electronic products, such as mobile phones, digital cameras, and personal digital assistants (PDAs). The liquid crystal display panel comprises a pixel structure. Referring to
In displaying a black-background white-frame image with the pixel structure 100, due to factors, such as panel warpage and positional shift of upper and lower substrates, light leakage may occur around the data line 20 so as to cause V-Crosstalk. Further, since relative positional shift occurs between the upper and lower substrates, an area with a large positional shift would result in a large area of darkness so that the black matrix on the substrate must be expanded in order to shield light leakage. This reduces the aperture ratio of the pixel. To increase the aperture ratio of the pixel, it is common to arranged the data line 20 beneath the separation electrode 40 at the interfacing of the domains 50. However, since in such an arrangement, the data line 20 is completely coincident with the separation electrode 40 of the pixel electrode 100, a relatively high parasitic capacitance would be caused between them. This leads to V-crosstalk in a grey-background white frame image.
The present invention provides a pixel structure and a liquid crystal display comprising the pixel structure, which help reduce an overlapping area between a data line and a pixel electrode located above the data line, reducing the parasitic capacitance between the data line and the pixel electrode and also reducing loading of the data line, increasing charging rate of the pixel, and alleviating V-crosstalk of a grey-background white-frame image.

In the embodiment of the present invention, each of the pixel electrodes 210, as a whole, is in the form of a rectangular plate that is located between two pixel common electrodes 240. The pixel electrode 210 is divided into two, upper and lower, pixel domains by a pixel electrode trunk 250. Preferably, each pixel electrode 210 is divided by the pixel electrode trunk 250 into two pixel domains that are symmetric in a vertical direction. In other others, the two pixel domains are symmetric in the vertical direction with respect to the pixel electrode trunk 250.
The data line 220 is arranged beneath the pixel electrode 210 and is perpendicular to the pixel electrode trunk 250. The data line 220 functions to transmit a grey level signal and the pixel electrode 210 drives the pixel in response to the grey level signal. The pixel electrode 210 is divided by the data line 220 into two, left and right, pixel domains, and preferably, each pixel electrode 210 is divided by the data line 220 into two pixel domains that are symmetric in a horizontal direction. In other words, the two pixel domains are symmetric with respect to the data line 220. In the embodiment of the present invention, since the data line 220 and the pixel electrode trunk 250 are perpendicular to each other, each pixel electrode 210 is divided by the data line 220 and the pixel electrode trunk 250 into four sub-pixel domains (as indicated by phantom lines of
In the embodiment of the present invention, the first sub-pixel domain 211 and the second sub-pixel domain 212 are symmetric with respect to the data line 220; and the third sub-pixel domain 213 and the fourth sub-pixel domain 214 are symmetric with respect to the data line 220.

The first sub-pixel domain 211, the second sub-pixel domain 212, the third sub-pixel domain 213, and the fourth sub-pixel domain 214 are each, as a whole, in the form of a rectangular plate but not limited thereto. In the embodiment of the present invention, the first sub-pixel domain 211, the second sub-pixel domain 212, the third sub-pixel domain 213, and the fourth sub-pixel domain 214 are each provided with a plurality of slits 215. The plurality of slits 215 separate each of the sub-pixel domains into a plurality of strip-like separated tabs 216 in such a way that the plurality of slits 215 and the plurality of separated tabs 216 are arranged and distributed alternately. Preferably, the plurality of slits 215 has open widths that are identical, meaning the distance between any two adjacent ones of the separated tabs 216 is identical; and the plurality of separated tabs 216 has widths that are identical, meaning the distance between any two adjacent ones of the slits 215 is identical.

The slits 215 of the third sub-pixel domain 213 and the corresponding slits 215 of the fourth sub-pixel domain 214 are jointed to and in communication with each other at locations above the data line 220 and are symmetric with respect to the data line 220; the separated tabs 216 of the third sub-pixel domain 213 are connected to the corresponding separated tabs 216 of the fourth sub-pixel domain 214 at locations above the data line 220 and are symmetric with respect to the data line 220. The first sub-pixel domain 211 and the third sub-pixel domain 213 are symmetric with respect to the pixel electrode trunk 250 so that the slits 215 and the separated tabs 216 of the first sub-pixel domain 211 and the slits 215 and the separated tabs 216 of the third sub-pixel domain 213 respectively corresponding thereto are symmetric with respect to the pixel electrode trunk 250; the second sub-pixel domain 212 and the fourth sub-pixel domain 214 are symmetric with respect to the pixel electrode trunk 250 so that the slits 215 and the separated tabs 216 of the second sub-pixel domain 212 and the slits 215 and the separated tabs 216 of the fourth sub-pixel domain 214 respectively corresponding thereto are symmetric with respect to the pixel electrode trunk 250.
In the embodiment of the present invention, since the slits 215 of the first sub-pixel domain 211 and the corresponding slits 215 of the second sub-pixel domain 212 are jointed to and in communication with each other at locations above the data line 220 and the slits 215 of the third sub-pixel domain 213 and the corresponding slits 215 of the fourth sub-pixel domain 214 are jointed to and in communication with each other at locations above the data line 220, the interfacing between the first sub-pixel domain 211 and the second sub-pixel domain 212 and the interfacing between the third sub-pixel domain 213 and the fourth sub-pixel domain 214 that are located above the data line 220 both is composed of alternately arranged slits having a predetermined width. Thus, the overlapping area between the data line 220 and the pixel electrode 210 located above the data line 220 is reduced. This reduces parasitic capacitance between the data line 220 and the pixel electrode 210 and also alleviates V-crosstalk of a grey-background white-frame image.

In the embodiment of the present invention, the gate lines 230 are arranged at two opposite ends of the pixel electrode 210 (namely parallel to a short side direction of the pixel electrode 210) and are spaced from the pixel electrode 210 by a predetermined distance. The gate line 230 at the two opposite ends of the pixel electrode 210 are parallel to each other and are perpendicular to the data line 220 and the pixel common electrode 240. The gate lines 230 are on the same metal layer as the material that makes the pixel common electrode 240.
The pixel common electrodes 240 supply a common electrode voltage to the pixel. In the embodiment of the present invention, the pixel common electrodes 240 are arranged at the other two opposite ends of the pixel electrode 210 (namely parallel to a long side direction of the pixel electrode 210) and partly and respectively overlap edge portions of the two opposite ends of the pixel electrode 210.
