A driving method of an electrophoretic display having at least a display particle is provided. The driving method includes the following steps. A first voltage difference is applied to a data line in a first period, in which the data line corresponds to one of the display particles. At least a particle restore period is inserted in the first period, and a second voltage difference is applied to the data line in the particle restore periods, in which the second voltage difference is different from the first voltage difference. With this method disclosed here, the maxima brightness, maxima darkness, contrast ratio, color saturation, bistability, and image updating time can be largely improved.

A touch panel includes at least a warning sensor. When an external force applied onto the touch panel reaches a predetermined strength so as to contact a top warning electrode to a bottom warning electrode, the warning sensor will be turned on in order to warn the user to reduce the external force so as to prevent the touch panel from being damaged by the external force.

A LCD panel comprises a first substrate and the second substrate. The first substrate comprises a pixel, a sensor pad arranged adjacent to the pixel, a switch electrically coupled to the sensor pad, a pixel gate line electrically coupled to the pixel, a sensor gate line electrically coupled to the switch, and a readout line. The second substrate comprises a sensing device protruding form the second substrate, and a conducting layer covering on the sensing device and electrically coupled to a predetermined power. When assembling the second substrate with the first substrate, the sensing device is opposite to the sensor pad. When pressing the second substrate, the conducting layer covering on the sensing device contacts with the sensor pad. The sensor gate line controls on/off state of the switch to determine whether the sensor pad is electrically conducted with the readout line.

A shift register including shift register units controlled by first and second clock signals for generating an output signal. For each unit, in an active period, the first driving device drives the first switch device to activate the output signal, and the second driving device provides a voltage signal according to the first clock signal to drive the first switch device to de-activate the output signal. When the first switch device de-activates the output signal, the second switch device provides the voltage signal to serve as the output signal according to the second clock signal. In the active period, the voltage signal has a low level, and the first and second clock signals are set as alternating-current signals and are opposite to each other. In a blanking period, the voltage signal has a high level, and each of the first and second clock signals is set as a direct-current signal.
