Abstract: According to an aspect, a display device includes an image display unit in which pixels each including a plurality of sub-pixels are arranged in a matrix, and a color converting unit that performs color conversion to reduce power consumption in the image display unit. The color converting unit does not perform the color conversion when total power consumption obtained by adding up the power consumption in the image display unit and power consumption in the color converting unit in a case where the color conversion is performed exceeds the power consumption in the image display unit in a case where the color conversion is not performed.

Abstract: According to an aspect, a display device includes: a controller; and a pixel including: first to fourth sub-pixels including respective first to fourth color filters transmitting light having respective spectrum peaks falling on a spectrum of reddish green, a spectrum of bluish green, a spectrum of red, and a spectrum of blue, respectively. The first to fourth sub-pixels each include a reflective electrode reflecting light transmitted through the color filter. The first to fourth sub-pixels are each divided into sub-divided pixels having different areas to perform multiple gradation expression through a combination of whether each of the sub-divided pixels reflects light. The controller stores patterns of combinations of whether each of the sub-divided pixels reflects light according to an input signal, and controls operations of the sub-divided pixels through use of any one of the patterns based on a predetermined condition including light intensity.

Abstract: According to an aspect, a display device includes: a display unit; a lighting unit emitting internal light; a measurement unit; and a control unit controlling an intensity of the internal light and a gradation value of each pixel in the display unit. The control unit calculates a required luminance value for a luminance value of a pixel to be N times as high as a luminance value indicated by an input signal, the pixel performing output with the largest gradation value out of the pixels in a predetermined image display region. The control unit determines the intensity of the internal light based on an intensity of the external light measured by the measurement unit and the required luminance value, and calculates an output gradation value based on the gradation value indicated by input signal, the intensity of the external light, and the intensity of the internal light.
