Abstract
An electronic device includes: a display driver integrated circuit (IC) configured to transmit image data to a display; and a host coupled to the display driver IC through a first interface and a second interface, wherein the host is configured to transmit the image data to the display driver IC through the first interface and transmit a mode switching signal to the display driver IC through the second interface, wherein the mode switching signal indicates whether the image data is to be transmitted in a command mode or in a video mode.
Claims17
An electronic device, comprising:
- a display driver integrated circuit (IC) configured to transmit image data to a display;
- and
- a host coupled to the display driver IC through a first interface and a second interface,
- wherein the host is configured to transmit the image data to the display driver IC through the first interface and transmit a mode switching signal to the display driver IC through the second interface, wherein the mode switching signal indicates whether the image data is to be transmitted in a command mode or in a video mode,
- wherein the host is configured to transmit moving image data to the display driver IC during at least one high-level period of a Tearing Effect (TE) control signal until still image data is capable of being transmitted to the display driver IC.
A method of driving an electronic device including a display driver integrated circuit (IC), the method comprising:
- receiving, by the display driver IC, a mode switching signal indicating whether image data is to be transmitted in a command mode or in a video mode from a host;
- outputting image data to a display through a memory buffer in response to the mode switching signal indicating the command mode, and outputting the image data to the display by bypassing the memory buffer in response to the mode switching signal indicating the video mode,
- wherein the image data is received from the host through a first interface, and the mode switching signal is received from the host through a second interface;
- and
- transmitting, by the host, moving image data to the display driver IC during at least one high-level period of a Tearing Effect (TE) control signal until still image data is capable of being transmitted to the display driver IC.
A method of driving an electronic device including a host, comprising:
- determining, by the host, whether or not image data is to be transmitted in a command mode or in a video mode based on the image data;
- and
- transmitting the image data and a mode switching signal indicating the command mode or the video mode to a display driver integrated circuit (IC),
- wherein the image data is transmitted through a first interface, and the mode switching signal is transmitted through a second interface;
- and
- transmitting, by the host, moving image data to the display driver IC during at least one high-level period of a Tearing Effect (TE) control signal until still image data is capable of being transmitted to the display driver IC.
