Abstract
An electronic device according to an example embodiment includes: a touch panel configured to sense a touch input; a display panel configured to output an image; a touch and display driver integration (TDDI) configured to control the touch panel and the display panel; and an interface circuit for data interfacing with a host, wherein the TDDI is configured to receive touch firmware data from the host via the interface circuit, and manage the touch firmware data by using at least one of a first volatile memory included in the interface circuit and the TDDI.
Claims20
An electronic device, comprising:
- a touch/display module configured to sense a touch input, and output an image;
- a touch and display driver integration (TDDI) chip configured to control the touch/display module;
- and
- an interface circuit including a first interface for receiving touch firmware data and image data from a host,
- wherein the TDDI chip is configured to receive the touch firmware data from the host via the first interface, and execute touch firmware by storing the touch firmware data in a first volatile memory included in the TDDI chip.
An operation method of a touch and display driver integration (TDDI) chip, comprising:
- receiving, from a host, a set signal having a first value for register setting to a first mode;
- receiving, from the host, first data via a first interface;
- recognizing that the first data is touch firmware data;
- storing the first data in a first volatile memory;
- receiving, from the host, the set signal having a second value for register setting to a second mode;
- receiving, from the host, second data via the first interface;
- recognizing that the second data is image data;
- and
- storing the second data in a second volatile memory.
