    摘要: After a look-up table applies γ correction to each of R, G, and B signals, a multiplier multiplies a γ corrected signal by a gain. An adder adds an offset to an output of the multiplier and supplies a resultant gain/offset corrected signal to a display panel. Memories store entropy coded correction data, which can be expanded by corresponding expansion circuits and supplied to the multiplier and the adder, respectively.

    摘要: During image display, pixel current measurement for brightness irregularity correction is carried out. Display is carried out by sequentially writing pixel data in a horizontal direction to pixel sections that are arranged in a matrix shape. Horizontal power supply lines PVDD are arranged for each horizontal line, and power is supplied from these power supply lines to corresponding pixel sections. When carrying out measurement of pixel current by lighting pixel sections one at a time, a horizontal power supply line PVDD of a horizontal line to which the lit pixel belongs is connected to a power supply PVDDb by a switch, and other horizontal power supply lines PVDD are connected to PVDDa.

    摘要: A display area of a display panel is divided into a plurality of areas, and a current detector detects a driving current (i.e. CV current) that flows when light is emitted from an area or a block including a plurality of areas. Such current detection is repeated while sequentially changing the target area or block and a CPU detects an area that has a current value different from that of other areas (i.e. an area that requires correction) based on results of the results of current detection. A similar process is performed on smaller areas obtained by subdividing the area to find a smaller area that requires correction. Thus, a correction value is obtained for each pixel and the correction values are efficiently calculated.
