A method and a detection circuit for selecting a touch detection time are provided. The method for selecting a touch detection time includes the following steps: detecting a noise signal of a touch panel in a first display frame period; determining whether signal strength of the noise signal in a first time segment in the first display frame period is greater than a first noise threshold; and when the signal strength of the noise signal in the first time segment in the first display frame period is less than the first noise threshold, performing touch control in a second time segment in a second display frame period corresponding to the first time segment.

Method and detect circuit for selecting touch detection time

A driving method for driving a display apparatus including a plurality of pixels, a plurality of data lines and a data driver. The data driver includes a first latch outputting a first sample data signal to a second latch, the second latch, a first charge sharing line and a second charge sharing line. The method includes performing a first charge sharing when a polarity of one of the pixels changes so as to output a first calibrated data signal to the data line electrically coupled to the pixel, and executing a second charge sharing when the most significant bit of the first sample data signal is different from the most significant bit of the second sample data signal so as to output a second adjusted data signal to the data line.

Data driver and display device driving method

A power management method and a power management device for a display are disclosed, including: comparing contents in an original frame image with contents in a previous image to generate a plurality of successive second periods with first stages and second stages, shortening a plurality of time intervals in the first pulse timing distribution and outputting the first pulse timing distribution for displaying a first sub-frame image on the display during the first stage of one of the plurality of successive second periods, and shortening a plurality of time intervals in the second pulse timing distribution and outputting the second pulse timing distribution for displaying a second sub-frame image on the display during the first stage of the other one of the plurality of successive second periods; and turning off the driving circuit of the display in the second stages.

Power management method and power management device

A display is provided. The display includes a first timing controller, a second timing controller and drivers. The first timing controller receives and transmits a first portion of pixel values, in which the first portion of the pixel values includes the pixel values of at least two non-adjacent pixels. The second timing controller receives and transmits a second portion of the pixel values, in which the second portion of the pixel values includes the pixel values of at least two non-adjacent pixels. Each of the drivers receives respectively a part of the first portion of the pixel values transmitted by the first timing controller and a part of the second portion of the pixel values transmitted by the second timing controller. A method of transmitting image data in the display is also disclosed.
