    摘要: An EL light-emitting element is driven digitally to reduce power consumption using a pixel having three transistors and two capacitors. A reset transistor for diode connection writes the threshold voltage of the drive transistor onto a coupling capacitor. The data voltage plus threshold voltage is then written onto the gate of the drive transistor. This reduces the amplitude of the data voltage required, further reducing power consumption.

    摘要: To alleviate an afterimage phenomenon caused by a hysteresis characteristic of a drive transistor. Current driven type light emitting elements 3 are provided for each of pixels 6 that are arranged in a matrix shape, and current of the light emitting elements 3 is controlled using drive TFTs 2 that operate by receiving data voltage on a gate. At least two power supply voltages (PVDDa, PVDDb) for supply to each pixel are provided, one being set to a voltage such that current corresponding to a data voltage flows in the drive TFT 2, the other being set to a voltage beyond a variation range of data voltage and that reverse biases the drive TFT 2, and the two power supply voltages are switched and supplied to each pixel 6.

    摘要: A display device which effectively reduces the occurrences of a false contour is provided. A driver digitally drives each pixel by obtaining a plurality of bit data from pixel data for one pixel to assign the plurality of bit data to a corresponding subframe; configuring one frame with a predetermined number of unit frames; and supplying corresponding bit data in each unit frame to each pixel. Specifically, an analyzing circuit 5-5 predicts a probability of occurrence of a false contour in one screen of the video signal based on the presence or absence of a true contour. A display method based on the video signal is set in accordance with an analysis result.
