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： Embodiments relate to an organic EL panel comprising a panel driving circuit for converting R′G′B′W data into driving signals which is supplied to a pixel circuit. At a RGB→R′G′B′W converting section, the bit width of input RGB data is greater than the bit width of converted R′G′B′W, and the characteristic curve of the amount of luminescent of W sub pixel for the input data of W in the said panel driving circuit is different from the R′G′B′ curve normalized at a luminance ratio necessary for a reproduction of white color with sub pixels of RGB. An appropriate process is carried out by the RGB→R′G′B′W converting section in accordance with the curve of input data from the panel driving circuit verses amount of luminescent to minimize an error which may be generated when a conversion is made.

摘要： An object of the invention is to convert input RGB data to R′G′B′W data without suffering loss of gradations of the input RGB data. A display panel 12 is configured having unit pixels made up of subpixels of RGBW (red, green, blue, white). In an RGB→R′G′B′W conversion section 10, conversion is carried out under conditions that usage rate of W is less than 100%, and a bit width of input RGB data us larger than a bit width of R′G′B′W data after conversion. In the RGB→R′G′B′W conversion section 10, R1G1B1values and W values are determined so that an absolute value of a sum of values obtained by multiplying differences between respective RGB data input and respective RGB components in R′G′B′W data after conversion by a weight, becomes minimum.

摘要： There is provided a display device in which disadvantageous effects due to unnecessary operations of an image lag alleviating function are minimized. In a display device of active matrix type, for each of the pixels arranged in a matrix, a current-driven emissive element is provided, and the current of the emissive element is controlled using a drive TFT so as to perform display. While a black display period during which an opposite bias voltage is applied between the gate electrode and the source electrode of the drive TFT is inserted in order to alleviate image lag, this insertion is performed only when a predetermined condition is satisfied, and is performed for a certain duration according to a command by a microcomputer (10).
