Abstract

An active matrix display device, including a pixel array with unit pixel provided with at least one memory pixel, having a 1-bit memory, arranged in a matrix formation, including at least one of a gate selection decoder for selecting gate lines of the pixel array, and a data selection decoder for selecting a data line.

Claims (16)

1 . An active matrix display device, including a pixel array with unit pixel provided with at least one memory pixel, having a 1-bit memory, arranged in a matrix formation, comprising:

at least one of a gate selection decoder for selecting gate lines of the pixel array, and a data selection decoder for selecting a data line.

2 . The active matrix display device of claim 1 , wherein the memory is static memory.

3 . The active matrix display device of claim 1 , wherein:

the decoder comprises a selection circuit, with transistors of the same type connected in series, one end being connected to a selection power supply and the other end being connected to a gate line;

a non-selection circuit, with transistors of the same type as the selection circuit connected in parallel, one end being connected to a non-selection power supply and the other end being connected to a gate line; and

the selection circuit and the non-selection circuit receive input of one group of signals selected from address data and a complement of the address data, and the single group if signals input to the selection circuit and the non-selection circuit have a complementary relationship.

4 . The active matrix display device of claim 1 , wherein the selection circuit has selection voltage control means for outputting different selection voltages for reading and writing.

5 . The active matrix display device of claim 1 , wherein the decoder is formed on the same substrate as the memory pixels.

6 . The active matrix display device of claim 1 , wherein the memory pixels include an organic EL element.

7 . An active matrix display device, having unit pixels arranged in a matrix shape, for controlling display of these pixels, wherein:

the unit pixels are provided with a plurality of memory pixels having a single bit memory, and the plurality of memory pixels are arranged in two or more rows, with a power supply being wired corresponding to each row of memory pixels.

8 . The active matrix display device of claim 7 , wherein the memory of the memory pixels is static memory.

9 . The active matrix display device of claim 7 , wherein power supply lines that are connected to pixels arranged adjacently in a row direction or column direction arranged inside the unit pixels have different wiring widths from each other.

10 . The active matrix display device of claim 7 , wherein voltages supplied to power supply lines that are connected to pixels arranged adjacently in a row direction or column direction arranged inside the unit pixels are different from each other.

11 . The active matrix display device of claim 7 , wherein an area where light is emitted to outside in a pixel arranged inside the unit pixel is different from at least some of the adjacent pixels in the row direction and column direction.
