    Abstract: According to an aspect, a display device comprising a display unit that produces a display output corresponding to an input signal. The display unit combines the display output corresponding to each of four or more colors. The display unit includes a plurality of pixels each including three or more sub-pixels, the number of which is smaller than the number of colors. The pixel includes, as the sub-pixels, one first sub-pixel having largest display region among the sub-pixels and two or more second sub-pixels each having a display region smaller than that of the first sub-pixel. One of the second sub-pixels outputs a high luminance color having highest luminance among the four or more colors.

    Abstract: A display device 10 includes are arranged in a matrix form and to which image information is input, and a signal processing unit 20. The signal processing unit 20 includes a rendering position deciding unit that decides whether or not a sub-pixel rendering process of changing input signal values of sub-pixels of a second pixel among a first pixel, the second pixel, and the third pixel is performed, a pattern information acquiring unit that acquires an arrangement of the sub-pixels in a processing direction of either of a portrait mode and a landscape mode as pattern information indicating a first arrangement pattern or a second arrangement pattern, and a rendering unit that performs a first sub-pixel rendering process or a second sub-pixel rendering process on the input signals of the sub-pixels of the second pixel based on the decision of the rendering position deciding unit and the pattern information.

    Abstract: A display device includes a signal processing unit that receives input signals, and calculates output signals to a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel. The signal processing unit calculates a frequency of pixels belonging to each of a plurality of partitions using a light quantity of a surface light source. The signal processing unit calculates an index value for each of the partitions by at least multiplying the cumulative frequency being obtained by sequentially adding the frequency of pixels from a partition having the maximum light quantity among the partitions, and the number of partitions representing a position of a partition to which the cumulative frequency belongs counted from the partition having the maximum light quantity. The signal processing unit controls luminance of the surface light source based on a partition in which the index value exceeds a threshold.
