摘要： A display recording information and generation method thereof are disclosed. The display recording information is used to record the corresponding relationship between the display information received by a driving IC of a display and pixels of the display. The display recording information is formed by one byte (8 bits). Its first bit through six bit record a counting result that a number counter or a column counter performs a six-bit counting on a number of pixels or a number of columns of pixels starting from 0; its seventh bit uses 0 or 1 to record that the counting result belongs to the number of pixels or a number of columns of pixels; its eighth bit uses 1 to record that a most significant bit of the display information including red, green, or blue is 1, otherwise uses 0 to record.

摘要： A ring oscillator clock automatic synchronization method of a panel driving circuit includes steps of: when a vertical blanking interval happens, a master driver generates a pulse signal to slave drivers respectively. A pulse width of the pulse signal equals to N times of a master ring oscillator clock, wherein N is larger than 0. When a slave driver receives the pulse signal, the slave driver uses its slave ring oscillator clock to count the pulse width of the pulse signal to obtain that the pulse width of the pulse signal equals to M times of the slave ring oscillator clock, wherein M is larger than 0. The slave driver compares M with N and automatically adjusts the slave ring oscillator clock according to the comparison result to make it achieve synchronization with the master ring oscillator clock.

摘要： A display apparatus and operating method thereof are disclosed. The display apparatus includes a display panel and a driving IC. A display area of the display panel is divided into sub-display areas. The driving IC is coupled to the display panel. The driving IC includes registers corresponding to the sub-display areas respectively. The driving IC receives a display data and obtains a plurality of color information corresponding to the sub-display areas respectively according to the display data, and then stores the plurality of color information in the registers respectively. When the frame display by the display panel has not to be refreshed, the driving IC stops receiving the display data and converts the plurality of color information stored in the registers into corresponding colors respectively and outputs them to the sub-display areas of the display panel to display.

摘要： A driver applied to a display apparatus is disclosed. The driver includes 2(N+1) source channels, M display lines, and an output polarity control module. N and M are positive integers. Polarity outputs of the M display lines are independently controlled and have no dependencies between each other. The output polarity control module provides (N+1) polarity inversion control signals. A K-th polarity inversion control signal of the (N+1) polarity inversion control signals controls polarities outputted by the (2K−1)-th source channel and the 2K-th source channel of the 2(N+1) source channels. K is a positive integer and 1≤K≤(N+1).
