Abstract: A luminance compensation method is provided. The luminance compensation method includes: establishing a time-varying luminance sequence according to an average luminance value of a plurality of sampled display devices in each unit time during an initial start-up period; establishing an operating luminance sequence according to an average operating luminance value of the sampled display devices under a plurality of different driving condition values after the initial start-up period; generating a driving condition value look-up table according to the time-varying luminance sequence and the operating luminance sequence; and obtaining compensation driving condition values in each unit time according to the driving condition value look-up table and the time-varying luminance sequence and accordingly establishing a time-varying compensation sequence, such that a display device drives a backlight module according to the time-varying compensation sequence in each time unit during the initial start-up period.

Abstract: A method for transmitting continuous data from a transmitter includes sensing a continuous touch trace on the touch device of the transmitter, generating touch data of the continuous touch trace according to sensing time, generating an initial point frame and a stroke frame according to the touch data of the continuous touch trace, transmitting the initial point frame and the stroke frame to a receiver. The initial point frame includes a first initial tag, coordinates of an initial point, and a terminating tag. The stroke frame includes a second initial tag, a plurality of offset data frames, and a total number of the offset data frames. Each offset data frame includes a horizontal offset value relative to a previous horizontal coordinate and a vertical offset value relative to a previous vertical coordinate.
