Abstract: A display panel of the present application comprises a driving module. The driving module controls a scan line connected to a sub-pixel to provide a scan signal, and a precharge signal sent earlier than the scan signal. A data signal has the same polarity when the scan line is providing the precharge signal and the scan signal. When the display panel is being driven, the precharge signal can be provided to the sub-pixel before the scan signal is provided to the sub-pixel, and when the polarity of the data signal is the same as the polarity of the data signal when the scan signal is provided to the sub-pixel, so as to turn on and precharge the sub-pixel.

In a display period, the voltage of the first gate is equal to the sum of the first difference and a second difference between the reference voltage and the data signal.
Abstract: An apparatus, method and computer program product provide a simplified method for unlocking an electronic device that uses soft keys, such as capacitive touch keys, or proximity detection areas and patterns. The keys may be implemented in the form of areas of a sensor, and a processing circuit observes a touch pattern (or proximity pattern, or characteristic pattern such as a capacitance pattern of a user's finger) and compares the same with the registered pattern to determine if there is a likeness. In doing so, the electronic device is operated at a low power state, and in that low power state observes whether a predetermined pattern is observed and when it is, unlocks the electronic device for interaction with a user at a fully operational state. By operating in the low power state while waiting to observe a predetermined pattern before unlocking the user interface, the device does not waste power on false positive detections, and allows for convenient wakeup and accessibility by a user.
