摘要:
A circuit for amplifying a display signal transmitted to a repair line by using a non-inverting amplifier is disclosed, which comprises a voltage follower, a non-inverting amplifier, a repair line, a thin film transistor (TFT) and a liquid crystal (LC) capacitor. The voltage follower is electrically connected to a data driver chip to thereby provide a display signal to the non-inverting amplifier. The non-inverting amplifier amplifies the display signal to thus obtain an amplified display signal, and transmits the amplified display signal to the TFT and the LC capacitor through the repair line. The amplified display signal is kept at a desired voltage level when the LC capacitor receives the amplified display signal.

A panel module and the power saving method used thereon, which use a timing controller to receive and compare a first frame image data and a second frame image data in order to obtain an image data comparison result and accordingly determine whether a plurality of source drivers, a plurality of gate drivers and a DC-DC converter have to enter a power saving mode.
摘要:
A timing controller including a memory and a memory controller is provided. The memory includes an odd-field block and an even-field block. The memory controller is coupled to the memory and controls the memory. When two of a first, a second and a third gate output enable signals output by the timing controller are active, the memory is controlled to output the data of the (I−1)th scan line stored in the odd-field block. When one of the first, the second and the third gate output enable signals output by the timing controller is active, and the other two signals are inactive, the memory is controlled to output the data of Jth scan line stored in the even-field block and write an odd-field field data of the (J+1)th scan line to the odd-field block and write an even-field field data of the (J+1)th scan line to the even-field block.

摘要:
A liquid crystal module for flat panel display comprising a glass substrate, a plurality of source drivers, a control board, and at least one bus. The source drivers coupled to the glass substrate utilize the chip on glass (COG) technology. The control board receives a plurality of data signals, a power signal and a gamma correction signal. The at least one bus coupled to the control board and at least one source driver, passes the data signals, the power signal and the gamma correction signal. The source drivers couple to the control board via the bus, each receiving a corresponding data signal. The data signals, conforming to transistor-transistor logic (TTL) standard, are transmitted sequentially on the bus.
