摘要： In a display device and a display driver, when a grayscale of a display image is equal to or lower than a specific grayscale value obtained from a histogram of the display image, a display grayscale is extended with a linear function. On the other hand, when a grayscale of a display image is equal to or higher than the specific grayscale value, histogram equalization of a part higher than the specific grayscale value is performed, and the display grayscale is extended with a non-linear function obtained from the histogram equalization.

The liquid crystal driving device includes a liquid crystal driving circuit, a backlight control unit, and display data expansion circuits. The liquid crystal driving circuit generates a liquid crystal driving signal to be supplied to a liquid crystal display panel in response to display data. The backlight control unit reduces driving current of the light emitting diode as a light source of the backlight module to illuminate the liquid crystal display panel, in response to the temperature rise of the liquid crystal display panel. The display data expansion circuit, in response to the temperature rise of the liquid crystal display panel, performs the data expansion of the display data, and compensates the contrast lowering of the liquid crystal display panel due to the dimming of the backlight module with the temperature rise of the liquid crystal display panel.

摘要： To provide a processing method for reducing motion blur while increasing resolution. By performing a super-resolution process, a resolution-increased image is obtained from an input image in multiple frames. By performing an enlargement process, an enlarged image is obtained from the input image in one frame. A high-frequency image is obtained by subtracting the enlarged image from the resolution-increased image. A high spatial frequency-emphasized image is obtained by adding the high-frequency image to the resolution-increased image. The enlarged image and high spatial frequency-emphasized image are displayed alternately every half frame.
