A display device includes a plurality of display area substrates, a common voltage generator and at least one AC voltage generator. The display area substrates are disposed in a display panel, wherein each of the display area substrates receives a gate line signal, a source line signal and a common voltage. The common voltage generator is coupled to the display area substrates for generating the common voltage to each of the display area substrates. The AC voltage generator is coupled to the common voltage generator, for generating an adjusting voltage to the common voltage according to driving current information of a plurality of source drivers of the display device, wherein the adjusting voltage has an AC voltage level.

Display device and control method thereof

A driving signal processing method for a large touch display integrated (LTDI) system is provided. The LTDI system includes plural LTDI chips that are concatenated. The LTDI chips include a master LTDI chip and plural slave LTDI chips. The driving signal processing method includes: receiving, by the LTDI chips, display data from a timing controller; and dispersedly outputting, by the master LTDI chip and at least one of the slave LTDI chips, M gate control signals respectively corresponding to M gate lines of a display panel of the LTDI system according to the display data during the display stage of the display panel.

Large touch display integrated system and driving signal processing method thereof

A driver circuit configured to drive a display panel to perform a display operation and a touch sensing operation is provided. The driver circuit includes a touch and display driver integration (TDDI) circuit and an external circuit. The TDDI circuit is configured to drive the display panel to perform the display operation and the touch sensing operation during a display period and a touch sensing period, respectively. The TDDI circuit outputs a reference signal. The external circuit is disposed outside of the TDDI circuit. The external circuit is configured to output a first output voltage and a second output voltage on the basis of the reference signal from the TDDI circuit. The first output voltage is larger than the second output voltage.
