Abstract: PROBLEM TO BE SOLVED: To achieve a trade-off between resolution and sensitivity, and pixel size or packing ratio and circuit complexity. SOLUTION: A circuit comprising a sensor 12, an amplifier connected by an output of the sensor 12 so as to control the amplifier, and a sensor-reset connected to the sensor 12 selectively resetting an electric charge in the sensor 12, and converting the data of the sensor 12 to an electrical signal can be improved by trading off the sensor-reset containing a reset-transistor with its channel region formed by a conductive material having a first structural state the amplifier containing an amplifier transistor 16 with its channel region formed by a conductive material having a converted first structural state, and the amplifier transistor 16 and the reset transistor formed on an common substrate.

Abstract: PROBLEM TO BE SOLVED: To provide a flexible two dimensional array. SOLUTION: In each pixel cluster of an array, two pixel columns 30a, 30b, 30c, 30d share a single gate line 32a, 32b, and each pixel row 34a, 34b' is connected to a single data line 36a, 36c, and thus, pixel sensor/display element 10A1 and 10B1 belong to the same pixel cluster. It is possible to connect two columns or rows of the pixel with one gate line or one data line by using TFTs of type A and type B as switches. the TFTs of type A and type B can have different turn-on characteristics such as n-channel and p-channel TFTs or different threshold voltages.
