Disclosed is a distribution of TFT components in the LTPS process. A pair of parallel data lines are arranged between an ith and (i+1)th rows of pixels. Each pair of data lines includes a first data line and a second data line. Two adjacent pixels of the ith row are respectively connected to the first data line and the second data line through corresponding U-shaped TFT components. Two pixels of the (n+1)th row corresponding to the two above adjacent pixels are respectively connected to the second data line and the first data line through corresponding U-shaped TFT components. The U-shaped TFT component of the pixel of the ith row and the U-shaped TFT component of the corresponding pixel of the (i+1)th row are disposed with openings thereof facing and staggered with each other. An aperture ratio of a product can be effectively increased by the staggered setting of the U-shaped TFT components. The use of such setting can realize dot inversion in the case of column inversion and reduce the power consumption of the product.
