  • Patent number: 9799275
    Abstract: Provided is a display device. The display device includes: a gamma mapping unit; a compensating signal generation unit including a limit gray scale determination unit outputting a white limit gray scale value; and a hue control compensation unit including a main color compensation unit and a white compensation unit. The white compensation unit decreases a gray scale value of the white image signal based on the white limit gray scale value to generate the white compensated signal and the main color compensation unit compensates the red, green and blue image signals based on the white limit gray scale value to generate the red, green and blue compensated signals, when gray scale value of the white image signal is larger than the white limit gray scale value.

    Abstract: A display substrate includes a base substrate, a high reflective layer, a metal light reflective layer and a low reflective layer. The high reflective layer is on the base substrate, and includes a high refractive layer and a low refractive layer which alternate with each other. The high refractive layer has a first refractive index, and the low refractive layer has a second refractive index smaller than the first refractive index. The metal light reflective layer is between the high reflective layer and the low reflective layer, and reflects a light. The low reflective layer comprises a light absorbing layer which absorbs a light, and at least one insulating layer. Accordingly, a light utilizing efficiency and a display quality may be increased.
