摘要： In a display apparatus of a hold type represented by a TFT liquid crystal display, blurring of dynamic picture when the dynamic picture is displayed is improved. One frame is divided into dark fields and light fields. A dark brightness gradation voltage approaching to display of black as near as possible is generated in the dark fields and a light brightness gradation voltage for compensating the brightness reduced by the dark fields is generated in the light fields. At this time, low gradation voltages (V0P to V20P) or high gradation voltages (V43P to V63P) in the dark or light brightness gradation voltages are set to the same potential.

摘要： Disclosed herein is a display device in which input data is written to a RAM as current frame data and read from the RAM as preceding frame data. Then, the current frame data and the preceding frame data are added up in a correction circuit and the result is subjected to an overdriving processing. After this, the processed (over-driven) data is assumed as current frame corrected data, which is then written to the RAM. The written corrected data is read from the RAM and subjected to a double-speed driving processing.

摘要： In RGB time division drives, there is capacitor coupling due to the effects of fluctuation in the drain lines, and thus, the image quality deteriorates (lateral smearing), so that the display brightness becomes different from the desired display brightness due to delay in the convergence of the fluctuation of the common potential, and thus, it is a goal to prevent the image quality from deteriorating (lateral smearing).In RGB time division drives, the order of time division is switched for each frame, or in the direction of the horizontal lines.
