A display IC chip includes a plurality of sides, a plurality of output terminals, two first color short-circuit lines, one second color short-circuit line, one third color short-circuit line, and conductive wires. The two first color short-circuit lines are parallel disposed in the IC chip and coupled to a first output terminal group of the output terminals. The second color short-circuit line is disposed between and parallel with the first color short-circuit lines. The second color short-circuit line is coupled to a second output terminal group of the output terminals. The third color short-circuit line is disposed between and parallel with the first color short-circuit lines. The third color short-circuit line is coupled to a third output terminal group of the output terminals. The conductive wires are coupled the first color short-circuit lines with the first output terminal group do not cross the second and third color short-circuit lines.

In a display panel module, a first group and a second group of data driver chips are separately cascaded on a first side of a display panel. A scan driver chip is disposed on a second side of the display panel. A first flexible printed circuit (FPC) is connected between a printed circuit board (PCB) and the display panel for transmitting signals to the first group of data driver chips, the second group of data driver chips and the scan driver chip, respectively.
摘要:
An LCD gate driver circuitry having a control circuit to adjust the driving current according to a bias control signal, wherein the control circuit comprises a plurality of PMOS switching elements connected in parallel and a plurality of NMOS switching elements connected in parallel. These switching elements form a plurality of PMOS/NMOS switching element pairs. Each of the pairs serves as a current booster stage in the gate driver circuitry. The “ON”/“OFF” state of each switching element pair is controlled by a separate bias signal so that the switching element pairs can be selectively turned on in order to adjust the driver current as needed. As such, the same gate driver circuitry can be used with different LCD panels.

A repair line framework of liquid crystal display is provided. By disposing part of the repair line inside the integrated circuit chip so that the routing of part of the repair line will penetrate through the integrated circuit chip before returning to the panel, or by routing part of the repair line disposed on the substrate within the display region so that the routing is positioned under the black matrix of the color filter, the routing length of the repair line is shortened and the impedance of the repair line is reduced.

A display device capable of adjusting slew rate includes a display panel, a driving circuit, a storage unit, and a compensating circuit. The display panel includes a plurality of signal lines for signal transmission. The driving circuit is coupled to the display panel for generating driving signals to a signal line of the display panel based on a control signal and a corresponding compensating signal. Data related to each signal line and its corresponding compensating signal is stored in the storage unit. The compensating circuit, coupled to the storage unit and the driving circuit, receives the compensating signal from the storage unit and sends the compensating signal to the driving circuit.
