Abstract

The invention discloses a touch display driving circuit, an arithmetic circuit, a display device and an operation method thereof. The touch display device includes a touch display driving circuit, a touch computing circuit and a processor. In the normal mode, the touch computing circuit obtains the control right, so as to obtain touch sensing data about the touch display panel from the touch display driving circuit. In the burning mode, the processor provides the program code to the touch display driving circuit, and controls the touch display driving circuit to obtain the control right, and the touch display driving circuit burns the program code into the touch computing circuit.

Description

technical field [0001] The present invention relates to a touch display device, in particular to a touch display device and an operation method thereof which can improve the area utilization rate of a touch display driver chip. Background technique [0002] In the application of an in-cell touch panel, the touch panel is usually configured with a touch display driver integration (Touch with Display Driver integration, TDDI) chip to realize the functions of touch and display. figure 1 It is a circuit block diagram of a known touch display device. like figure 1 As shown, the touch display device 100 is provided with a TDDI chip 11 and a touch display panel 12 . In order to make the touch display panel 12 achieve the design effect of a narrow frame, components such as a microcontroller (MicroControl Unit, MCU) and a static random-access memory (Static Random-Access Memory, SRAM) need to be arranged in the TDDI in a narrow and long arrangement. In the chip 11, this will incre...
