A driving method of an electrophoretic display is provided. The driving method includes the following steps. A plurality of pixels of a display panel of the electrophoretic display are configured as a plurality of blocks. A common voltage of the display panel is set to a first voltage. A plurality of scanning signals are inputted to a plurality of scanning lines of the display panel in order in which scanning lines corresponding to the same block receives the same scanning signal. A plurality of data lines of the display panel are measured to obtain at least one peak voltage corresponding to each of the blocks. A feed through voltage corresponding to each of the blocks is determined according the peak voltages corresponding to the blocks. A plurality of driving signals which drive each of the blocks are adjusted according the feed through voltage corresponding to each of the blocks.

The touch control system with multi-touch detection functions includes a touch panel, a first transceiver, a second transceiver, and a processor. The first transceiver scans N first sensing lines along a first axis of a touch panel, and detects at least one first sensing line touched by at least one object according to the scanning result. The first transceiver inputs at least one high frequency signal to the at least one first sensing line touched by the at least one object, and the second transceiver inputs M low frequency signals to M second sensing lines along a second axis of the touch panel. The processor receives and detects M feedback signals of the M second sensing lines along the second axis, and determines a position of at least one touch point according to the M feedback signals.

A capacitive touch panel comprises a touch detection array having rows of first direction detection units and columns of second direction detection units, shared scan lines, independent scan lines and a driver control module. The first direction detection units are divided into a first group and a second group of rows arranged in an alternating manner. Each shared scan line is connected to one row of the first direction detection units in the first group and one column of the second direction detection units. Each independent scan line is connected to one row of the first direction detection units or one column of the second direction detection units that is not connected to the shared scan lines. The driver control module is connected to the shared scan lines and the independent scan lines to perform scanning processes to detect a touch input. A touch detection method is also disclosed.

A display method of an electrophoresis display (EPD) device having a display area and a plurality of pixels located in the display area is provided. In the display method, firstly, the display area is divided into a plurality of unit areas. A plurality of pixels exist in each of the unit areas. Then, in some unit areas, at least two pixels in each of the unit areas are enabled to respectively display a first color and a second color, such that the first colors and the second colors are mixed to achieve a mixed color in vision. The first color has a maximum gray-level value. The second color has a minimum gray-level value. A gray-level value of the mixed color is between the maximum gray-level value and the minimum gray-level value.

A portable electronic device includes a screen module, a main body module, and an input/output module. The screen module is connected with the main body module. The input/output module is electrically connected with the main body module. The input/output module is pivotally connected with the screen module and close to the bottom. When the screen module is rotated relative to the main body module to be opened, the front end of the input/output module is driven to lift to drive the input/output module to be out of a state that the input/output module abuts against the main body module. Therefore, the portable electronic device is easy to be operated. Moreover, the heat dissipation is improved to keep the internal temperature low and reduce energy consumption.

A timing controller is provided. The timing controller comprises a data analyzer, a gain processor, an operator unit and an original gamma voltage generator. The present invention utilizes the data analyzer to analyze a gray level distribution of video data, and then the gain processor selects a gain value. The operator unit converts an original gamma voltage produced by the original gamma voltage generator into an actual gamma voltage according to the gain value. Therefore, the present invention adaptively adjusts the gamma voltage according to the gray level distribution of the video data for increasing display quality.
