A touch panel includes a substrate and a first electrode array. The first electrode array is disposed on the substrate and includes first and second touch regions. The first electrode array further includes first, second, third, and fourth electrodes. The first electrode is disposed on the first touch region. The second electrode is disposed on the first touch region corresponding in position to the first electrode. The third electrode is disposed on the second touch region. The fourth electrode is disposed on the second touch region corresponding in position to the third electrode. In addition, the first to fourth electrodes are all disposed on the same layer. The first electrode is disposed diagonally to the fourth electrode, and the first electrode is electrically coupled to the fourth electrode. Furthermore, a method for controlling the touch panel is also disclosed herein.

Touch device, touch panel, and method for controlling the same

A touch panel includes a substrate, a plurality of first traces, an insulation layer, a plurality of second traces, and a microcontroller. The first traces are disposed over the substrate, the insulation layer is disposed over the first traces, and the second traces are disposed over the insulation layer. The microcontroller is electrically connected to the first traces and the second traces, and is operable to control the first traces and/or the second traces so that the first traces and/or the second traces form open loops or closed loops. Furthermore, a touch sensing method is also disclosed herein.

Touch panel and touch sensing method thereof

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.

Driving method and method for measuring feed through voltage of electrophoretic display

The present invention provides a dual-mode touch sensing apparatus. The dual-mode touch sensing apparatus includes a substrate, a first touch sensing electrode formed on the substrate and a second touch sensing electrode formed on the substrate. The first touch sensing electrode is used to perform the capacitive touch sensing technology. The second touch sensing electrode is used to perform the electromagnetic touch sensing technology.

Dual-mode touch sensing apparatus

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.
