    摘要： An organic light-emitting device includes a substrate, an anode and a cathode disposed over the substrate, and a light-emitting layer disposed between the anode and the cathode wherein the light-emitting layer includes a host and at least one dopant. The host of the light-emitting layer is selected to include a solid organic material including a mixture of at least two components wherein the first host component is an organic compound capable of transporting electrical charges and also forms an aggregate, and the second component of the mixture is an organic compound capable, of transporting electrical charges and, upon mixing with the first host component, is capable of forming a continuous and substantially pin-hole-free layer. The dopant of the light-emitting layer is selected to collect excitons and produce colored light, and an electron-transporting layer is disposed between the light-emitting layer and the cathode for providing improved electron injection and transport.

    摘要： Provided is a display device that includes an optical sensor having a high sensitivity in which a potential difference of an accumulation node due to an illuminance difference on a light receiving surface after boosting is set greater than a potential difference of the same at an end of an integration period. The display device includes an optical sensor in a pixel region. The optical sensor includes a diode D1; a reset signal line RST for supplying a reset signal; a readout signal line RWS for supplying a readout signal; an accumulation node having a potential (VINT) that varies with an amount of light received by the diode D1 during a period from supply of the reset signal to supply of the readout signal; an amplifying element C1 for amplifying VINT according to the readout signal; and a sensor switching element M2 for reading out the amplified potential and outputting the same to an output line. A potential of a light shielding film LS provided on a back side of the diode is fixed to a constant potential VLS satisfying the following formula: VLS≧VRST.H.

    摘要： A buffer circuit drives a capacitive load based on a voltage Vin. In a setup period, switches are in an ON state, and in a drive period, a switch is in an ON state. A voltage comparison unit compares the voltage Vin in the setup period and a voltage Vout in a drive period to output a comparison result voltage. A push-pull output unit includes a TFT for charge and a TFT for discharge. A drive control unit controls the TFTs to be in an OFF state in the setup period, and in the drive period, selectively controls the TFTs to be in an ON state in accordance with the comparison result voltage.
