Active matrix display and method of manufacturing the same
View Patent ↗There is provided an active matrix display including pixels arrayed in a matrix form and each including a display element and a thin film transistor. In each of columns which the pixels form, the pixels are divided into a first pixel group in which the thin film transistors are arranged along a first straight line parallel with the column, and a second pixel group in which the thin film transistors are arranged along a second straight line parallel with the column and spaced apart from the first straight line.
1. An active matrix display comprising pixels arrayed in a matrix and each including a display element and a polysilicon thin film transistor, wherein the pixels in each column of the matrix are arranged in a line and are divided into at least a first pixel group in which the polysilicon thin film transistors are arranged along a first straight line parallel with the column, and a second pixel group in which the polysilicon thin film transistors are arranged along a second straight line parallel with the column and offset from the first straight line, and wherein the polysilicon thin film transistor is a drive transistor, the drive transistor and the display element being connected in series between first and second power supply terminals.
2. The display according to claim 1 , wherein each of the pixels further includes a pixel switch which is connected between a video signal line and a gate of the drive transistor and whose switching operation is controlled by a scan signal supplied from a scan signal line, and a capacitor which is connected to the gate of the drive transistor.
3. The display according to claim 1 , wherein dispersion of mobilities of the thin film transistors is narrower in the first and second pixel groups than that in the column.
4. The display according to claim 1 , wherein the pixels in the first pixel group and the pixels in the second pixel group are alternately arranged in a direction parallel with the column.
5. The display according to claim 1 , wherein in each of the columns, the pixels in the same column are equal to each other in a position of the display element in a direction parallel with rows which the pixels form.
6. The display according to claim 5 , wherein in each of the columns, the pixels adjacent in a direction parallel with the column are different from each other in a relative position of the display element with respect to the polysilicon thin film transistor in the direction parallel with the rows.
7. The display according to claim 1 , wherein in each of the columns, the pixels adjacent in a direction parallel with the column are different from each other in a relative position of the display element with respect to the polysilicon thin film transistor in a direction parallel with rows which the pixels form.
