Abstract: The present disclosure provides a handwritten screen and a control display device. The handwritten screen includes a plurality of pixels arranged in an array, and a first substrate and a second substrate both being electrically insulating and thermally conductive. Each of the plurality of pixels includes a thermoelectric generator and a display unit connected with each other, the thermoelectric generator and the display unit are between the first substrate and the second substrate, and the thermoelectric generator generates an electric filed once there is a difference between a temperature of the first substrate and a temperature of the second substrate, so as to supply power to the display unit. The present disclosure effectively utilizes a difference in temperature between a finger (i.e., the first substrate) and an external environment (i.e., the second substrate) during touch, and converts thermal energy into electrical energy to perform thermoelectric power generation.
