Abstract: A sample holding circuit includes a signal input terminal, a first sampling unit, a second sampling unit, and a holding unit. The signal input terminal receives a first reference voltage or a second reference voltage, the first sampling unit samples the first reference voltage when a first clock signal is triggered to obtain a first sampling voltage, the second sampling unit samples the second reference voltage when a second clock signal is triggered to obtain a second sampling voltage. The holding unit receives the first sampling voltage and the second sampling voltage when a third clock signal is triggered. The sample holding circuit effectively simplifies circuit structure and reduces the use of amplifiers, also improving the signal to noise ratio.

Abstract: A time controller is able to convert and present the LCD display of gray levels within images with a brightness equal to that within the original images. The time controller alternates in operation between first and second modes of gamma correction, each for a specified time duration. In the first correction mode, the time controller corrects the original gray levels in a correction-positive manner and outputs first correction gray levels. In the second correction mode, the time controller corrects the original gray levels in a correction-negative manner, and outputs the second correction gray levels. The first correction gray level is equal to or larger than the second correction gray level, to correspond with original gray levels.

Abstract: A driving control circuit with a compensating circuit detects pixel driving circuits in a display apparatus for compensating a threshold voltage in the pixel driving circuits. The compensating circuit electrically connects with the pixel driving circuits through a corresponding monitoring line. The pixel driving circuit sequentially operates during a detecting time period and a displaying period. Each pixel driving circuit comprises a driving transistor and an OLED. During the detecting time period, the compensating circuit charges a node in each pixel driving circuit by a constant current for speeding up a time of the detecting time period. The node is connected between a terminal of the driving transistor and the OLED in each pixel driving circuit.
