Abstract

A pixel array and a display panel with the pixel array are provided. The number of the scan lines used in the pixel array is reduced to half, while the number of data lines is doubled because every two sub-pixel rows correspond to one scan line in the pixel array. The wire impedances between the data lines and the pixel array are thus made the same. The aperture ratio of each sub-pixel is thereby increased and the size of the TFT in each sub-pixel is also reduced. The complexity in the wire arrangement of the pixel array is accordingly lowered to improve the transmittance of the display panel and make the frame resolution of the display panel more even.
