first embodiment
[0031]FIG. 1A is a schematic top view of a pixel array according to the invention. FIG. 1B is an equivalent circuit diagram of the pixel array of FIG. 1A. FIG. 1C is a partial cross-sectional view of a pixel array substrate of FIG. 1 A along the line I-I′. With reference to FIG. 1A, FIG. 1B, and FIG. 1C, a pixel array substrate 100 includes a substrate 110, a plurality of scan lines SL1 and SL2, an insulating layer 130, a plurality of data lines DL1 (only one is depicted in the figure for clarity), a covering layer 150, and a plurality of pixel structures 171 and 172. For clarity, FIG. 1A, FIG. 1B, and FIG. 1C merely illustrate two of the pixel structures, i.e. 171 and 172, that are adjacent to each other in a Y direction. Those skilled in the art should understand that the pixel array substrate 100 in fact includes multiple pixel structures that are arranged in an array.
[0032]A material of the substrate 110 may be, for example, glass, quartz, or plastic. The substrate 110 is mainly...
sixth embodiment
[0048]FIG. 6A is a schematic top view of a pixel array according to the invention. FIG. 6B is an equivalent circuit diagram of the pixel array of FIG. 6A. FIG. 6C is a partial cross-sectional view of a pixel array substrate of
[0049]FIG. 6A along the line I-I′. With reference to FIG. 6A, FIG. 6B, and FIG. 6C, a pixel array substrate 600 is substantially similar to the pixel array substrate 100. Thus, identical elements are denoted by the same reference numerals, and details thereof will not be repeated hereinafter. The sixth embodiment of the invention is different from the above three embodiments mainly in the following aspects. In this embodiment, three adjacent pixel structures 173, 174, and 175 share the contact hole W. Active devices T3, T4, and T5 that are adjacent in the X direction and the Y direction are electrically connected to the same data line DL2 and are respectively driven by the scan lines SL1, SL2, and SL3. The active device T5 includes a gate G5, a source S5, a dra...
seventh embodiment
[0051]FIG. 7 is a schematic top view of a pixel array according to the invention. A pixel array substrate 700 is substantially similar to the pixel array substrate 600. Thus, identical elements are denoted by the same reference numerals, and details thereof will not be repeated hereinafter. The only difference between the pixel array substrate 700 and the pixel array substrate 600 lies in the shape of the contact hole W shared by the pixel electrodes PI3, PI4, and PI5. In the pixel array substrate 700, the shared contact hole W is L-shaped. Likewise, the design of the electrical connection through the common contact hole W improves the resolution (PPI) of a display product that uses the pixel array substrate 700 of this embodiment and reduces the influence that the area of the contact hole W causes to the pixel array substrate 700.
[0052]To sum up, in the pixel array of the invention, the scan lines or data lines or both, which correspond to adjacent pixel electrodes, are disposed on...
