20130057527 | DISPLAY DEVICE - Provided is a display device that is capable of ensuring a wide dynamic range of an optical sensor even in the case where an offset due to ambient temperature changes is compensated with use of an output of a reference element. The display device has optical sensors in a pixel region of an active matrix substrate ( | 03-07-2013 |
20130162602 | DISPLAY DEVICE WITH OPTICAL SENSOR - A plurality of sensor circuits each including an optical sensor and a charge retention transistor each provided between a reset line and an accumulation node are arranged in a pixel region of a display device. In a sensing period, a LOW-level voltage is applied as a reset cancellation voltage to the reset line RSTa, and a HIGH-level voltage is applied to a control line CLKa to control the charge retention transistor to be in an ON state. In a period other than the sensing period, the LOW-level voltage is applied to the control line CLKa to control the charge retention transistor to be in an OFF state, and the HIGH-level voltage is applied as a retention voltage to the reset line RSTa. Thus, a drain-source voltage Vds of the charge retention transistor is lowered, a leakage current through the charge retention transistor is reduced, and a light detection accuracy is enhanced. A substantially middle voltage between a reset voltage and a voltage at an accumulation node at the sensing of a maximum amount of light may be used as the retention voltage. | 06-27-2013 |
