Abstract:
A device for driving polarity inversion of electrodes of a liquid crystal display (LCD) panel includes a time sequence controller and a source driver. In order to drive polarity inversion of electrodes of the LCD panel, a polarity inverting signal is provided and a digital video data is outputted, wherein the polarity inverting signal has a frequency higher than a scan frequency of scan lines but lower than a display frequency of sub-pixels. Then, the digital video data is converted into an analog video data. The analog video data has a polarity inverting frequency substantially equal to the frequency of the polarity inverting signal.
Abstract:
A driving circuit for a double display panel is disclosed. The driving circuit drives a first display panel and a second display panel, and includes an ASIC and two pairs of driving ports. The ASIC outputs a driving signal pair including two signals which are opposite in phase to each other. A first pair of driving ports electrically connected to the first display panel and the ASIC, receiving the driving signal pair to determine whether to activate the first display panel or not. A second pair of driving ports electrically connected to the second display panel and the ASIC, receiving the driving signal pair to determine whether to activate the second display panel or not. The driving signal pair determining the activation of the first and second display panel is the same for both panels, and only one of the display panels can be activated at a time.
Abstract:
A driving method of an LCD panel having a driving IC and a plurality of display groups comprising a plurality of display cells and are respectively coupled to a data electrode and a gate electrode. The driving IC simultaneously drives one display cell in each display group on the same row. First, video signals are provided by the driving IC to one display cell in each display group on the same row. Here, the display cells of adjacent display groups receive opposite polarity video signals. Finally, the scan signals are provided to the gate electrodes.
Abstract:
An method for the partial display mode monitor, which is suitable for the monitor operation in the partial mode. In this method, the memory is first planned so that each pixel has one corresponding memory address in a plurality of memory addresses within the planned memory. A serial controller is used to detect and determine whether the original pattern in the display screen has been updated or not, wherein the original pattern is stored in the memory and also comprises some pixels which have corresponding memory addresses. Then, when the serial controller detects that the original pattern has updated to a new pattern, the new pattern is compared with the original pattern, so as to replace the original pattern, which is stored in the memory and its corresponding memory addresses, with the new pattern. Finally, the new pattern is output to the monitor.
