Display apparatus and liquid crystal display apparatus

摘要

A display apparatus includes: a panel including a plurality of pixels configured to display an image; an ambient light sensor configured to sense an illumination level of ambient light and to generate ambient light data; a gamma controller configured to control sections of a reference gamma curve based on the ambient light data to generate a controlled gamma curve, the controlled gamma curve defining output data according to input data; a data driver configured to convert an image signal into a data voltage based on the controlled gamma curve and to supply the data voltage to the pixels; and a gate driver configured to supply a gate signal to the pixels.

1. A display apparatus comprising:
a panel comprising a plurality of pixels configured to display an image; an ambient light sensor configured to sense an illumination level of ambient light and to generate ambient light data; a gamma controller configured to control a section of a reference gamma curve based on the ambient light data to generate a controlled gamma curve, the controlled gamma curve defining a relationship between output data voltages and input values; a data driver configured to convert an image signal into a data voltage based on the controlled gamma curve and to supply the data voltage to the pixels; and a gate driver configured to supply a gate signal to the pixels, wherein the section of the reference gamma curve corresponds to a range of input values more than or equal to a first input value and less than or equal to a second input value larger than the first input value, and wherein the range is broader as the illumination level of the ambient light increases.
