The disclosure provides a pixel circuit and a driving method thereof, a driving circuit, and a display device, which pertains to the field of pixel driving technology. The pixel circuit includes a capacitor, a capacitor charging transistor, a first and second capacitor discharging transistor. The capacitor is charged to a first voltage greater than the pixel voltage when the capacitor charging transistor is turned on. The capacitor is connected in series with the first and second capacitor discharging transistor to form a discharge circuit, and the capacitor is discharged when the first and second capacitor discharging transistor are turned on so that the voltage across the capacitor drops from the first voltage to the pixel voltage. There is no need to arrange a Gamma resistor for the driving circuit for the pixel circuit array provided by the disclosure, which makes the structure simple and the power consumption in driving low.

A manufacturing apparatus includes a manufacturing unit; a cover that includes a see-through portion; an input unit that occupies a predetermined area on a surface of the see-through portion and detects a contact to the predetermined area and outputs information regarding the detection; a display that displays a predetermined image at a position of the cover; and a controller that in response to a predetermined input to the input unit, controls the display to display the predetermined image at or near a position where the predetermined input is detected, controls the display to display a predetermined operation panel image as the predetermined image at or near a position on the cover that overlaps the input unit; and controls the manufacturing unit based on a detection position of the predetermined input on the predetermined operation panel image.

The present invention provides a data processing device connected with an intermission driving. The data processing device achieves a satisfactory power saving while ensuring a high level of display quality of the display device. Upon detection of non-data update in a frame buffer, the host calculates a next refreshing timing based on driving information obtained from a liquid crystal display device (LCD), sets a timer for a timeout after a length of time representing the calculated result, and then the host and the LCD shift to Intermission State 1. Thereafter, when the timer times out to bring the host back to Normal State and a data update at the frame buffer is detected, data for refreshing an display image in the LCD is transferred from the host to the LCD. If the amount of time representing the calculated result is longer than a predetermined baseline, a shift is made to Intermission State 2 which provides greater power saving than Intermission State 1.
