Patent ID: 8605069

Claim:
The image display device including a touch panel input function, comprising: a display unit comprised of a plurality of pixels each of which includes a self-luminous element; signal lines configured to input a display signal voltage to the pixel; a display control circuit configured to control the display signal voltage; detection lines configured to output a characteristic of the self-luminous element included in each of the pixels; a detection use power source for applying current to the self-luminous element; change-over switches; and a detection positional coordinates generation circuit, wherein the detection use power source is connected with the pixels through the detection lines and the change-over switches, wherein the detection lines are connected with the detection positional coordinates generation circuit through the change-over switches, and wherein the detection positional coordinates generation circuit configured to output temperature information and a coordinates signal corresponding to one of the pixels on which an input motion causes a temperature variation based on the characteristic of the self-luminous element included in each of the pixels, wherein a presence or absence of a touch panel input is determined in response to temperature information output by the detection positional coordinates generation circuit, and wherein the absence of touch panel input is determined if the temperature information output by the detection positional coordinates generation circuit is smaller than a first threshold value, the presence of touch panel input is determined if the temperature information is larger than the first threshold value or smaller than a second threshold value, a sliding motion is determined if the temperature information is larger than the second threshold value.
