摘要： A display method, device and a computer-readable medium are provided. The method includes: detecting whether there is any change in a displayed content for the display; in response to detecting that the displayed content for the display does not change, controlling the display to alternately update display data corresponding to a first portion and a second portion of display units in each row when the display unit comprises m rows of pixels; and in response to detecting that the displayed content for the display does not change, controlling the display to alternately update display data corresponding to a third portion and a fourth portion of display units in each column when the display unit comprises n columns of pixels. Herein m and n are positive integers. Thus, screen flicker caused by reduction of refresh frequency of a display while the display content does not change can be avoided.

摘要： First and second scanning signal line drive circuits provided in this liquid crystal display device perform interlacing drive. Gate clock signals, gate start pulse signals, and clear signals provided to these drive circuits are supplied through two trunk lines corresponding to two shift register circuits included in each of the drive circuits. Accordingly, when compared to a typical conventional scanning signal line drive circuit including one shift register circuit, the number of bistable circuits connected to one trunk line is halved and the clock signals have lower frequencies, whereby it is possible to further reduce power consumption.

摘要： According to the invention, a compact and inexpensive with low power consumption memory and low access speed can be used for a panel controller and a deterioration compensation circuit of a display device. In a display device of a digital gray scale method, a plurality of pixels of a display panel are divided into first to n-th pixel regions (n is 2 or more) and a format converter portion of a panel controller converts the format of only video data corresponding to one of first to n-th pixel regions and writes the data to one of first and second video memories in each frame period. A display control portion reads out video data that is converted in format and corresponds to one of first to n-th pixel regions in which video data is written to the other of the first and second video memories in the preceding frame period, and transmits the data to the display panel.
