摘要: A method of data transmission is provided. The method uses a differential data reverse signal to implement the differential data signal so that the number of the signal transitions can be effectively reduced in order to keep up with the data transmission rate. Further, because of using the differential data signals and the differential data reverse signal, the power consumption and the EMI can also be reduced.

摘要: A driving circuit used in a liquid crystal display device is disclosed which includes a timing controller, a source driver and a low color scale driving circuit. The timing controller outputs a polarity inverting signal, a first digital signal, a second digital signal, a third digital signal and a fourth digital signal. The low color scale driving circuit generates a first analog signal, a second analog signal, a third analog signal and a fourth analog signal according to the digital signals outputted from the timing controller for driving a liquid crystal panel. Through the low color scale driving circuit, power consumption of the liquid crystal display device reduces when operating in the condition of low color scale.

摘要: A display control device and a display control method for use in a portable electronic apparatus are disclosed. The portable electronic apparatus includes a main controller and a display panel. The display control device includes a digital data register in communication with the main controller for storing a digital data display signal received from the main controller, and a digital-to-analog converter in communication with the digital data register, converting the digital data display signal stored in the digital data register into an analog data display signal and outputting the analog data display signal to the display panel to be revealed. The main controller keeps on outputting refreshed digital data display signals in a normal mode, and suspends the output of any further digital data display signal in an idle mode. In the idle mode, the digital data register reiteratively outputs a last stored digital data display signal to the digital-to-analog converter.

摘要: A flip-cover mobile phone with cover-on talking capability. The phone has a plurality of buttons on the front surface of the phone but can be hidden away by the cover. The surface of the phone further includes a loudspeaker, a microphone, a communication on/off button and a touch-sensitive screen. Incoming calls can be received simply by pressing the communication on/off button so that talking is possible with the cover on. With the addition of a touch-sensitive screen, the phone may be operated without lifting the flip cover.

摘要: 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.

摘要: A method for driving a liquid crystal display device is disclosed. When data clock (DCLK) is not required, the method of driving a liquid crystal display device with low power consumption enables the close loop of the DCLK. That is, after a data transmission (LOAD) signal is triggered and before a data reception (DSTH) signal is triggered, the timing controller forces the DCLK signal to be at a low voltage level, which means the DCLK signal is not outputted, and therefore power saving is achieved.
摘要翻译: 公开了一种驱动液晶显示装置的方法。 当不需要数据时钟(DCLK)时,驱动具有低功耗的液晶显示装置的方法能够使DCLK闭合。 也就是说,在数据发送(LOAD)信号被触发之后并且在触发数据接收(DSTH)信号之前,定时控制器迫使DCLK信号处于低电压电平,这意味着不输出DCLK信号,以及 因此实现省电。
