THIN FILM TRANSISTOR ARRAY SUBSTRATE, DISPLAY PANEL THEREON, AND METHOD OF TESTING SINGLE COLOR IMAGE OF DISPLAY PANEL

摘要

A TFT array substrate which includes a plurality of pixels arranged in a matrix, has each pixel including sub-pixels in a 2×2 matrix. Two data lines are between neighboring columns of the sub-pixels and scan line is arranged between neighboring rows of the sub-pixels. The sub-pixels in same row can be electrically coupled to one scan line. The sub-pixels for the same color in one same column can be electrically coupled to the neighboring data line. The sub-pixels configured to display another same color in the same column can be electrically coupled to another neighboring same data line. Each two adjacent sub-pixels displaying a same color have opposite polarities.
