Abstract
A display driver integrated circuit includes a first slave module and a second slave module. The first slave module is initially set as a primary module to receive a mode conversion command, and is disabled based on the mode conversion command. The second slave module is initially set as a secondary module that does not receive the mode conversion command, and is set as the primary module instead of the first slave module when the first slave module is disabled. The first and second slave modules control processing or transfer of data through a channel included in or coupled to a display according to a predetermined protocol.
Claims18
A display driver integrated circuit (DDIC), comprising:
- a first slave module to be initially set as a primary module to receive a mode conversion command and to be disabled based on the mode conversion command;
- and
- a second slave module to be initially set as a secondary module that does not receive the mode conversion command and to be set as the primary module instead of the first slave module when the first slave module is disabled, wherein the first and second slave modules are to control processing or transfer of image data through a channel included in or coupled to a display according to a predetermined protocol corresponding to a mobile industry processor interface (MIPI) display serial interface, wherein the mode conversion command received by the primary module includes an enter_partial_mode command to indicate that a display module enters a partial driving mode, and wherein the primary module and the secondary module are to be enabled when the primary module receives a mode conversion command including an enter_normal_mode command indicating that the display module enters an entire driving mode.
A display module, comprising:
- a display panel divided into a plurality of sub display areas;
- and
- a display driver integrated circuit (DDIC) including a plurality of slave modules, one of the slave modules to be initially set as a primary module to receive a mode conversion command and another of the slave modules to be initially set as a secondary module which does not receive the mode conversion command, the slave modules corresponding to mobile industry processor interface (MIPI) protocol, wherein the mode conversion command received by the primary module includes:
- an enter_partial_mode command to indicate that the display module enters a partial driving mode, or
- an enter_normal_mode command to indicate that the display module enters an entire driving mode.
A display system, comprising:
- a host processor including a plurality of master modules;
- and
- a display module to be controlled by the host processor, the display module including:
- a display panel divided into a plurality of sub display areas;
- and
- a display driver integrated circuit (DDIC) including a plurality of slave modules corresponding to mobile industry processor interface (MIPI) protocol, the slave modules respectively connected to at least one of the master modules, one of the slave modules to be initially set as a primary module to receive a mode conversion command from the host processor, another of the slave modules to be initially set as secondary module that does not receive the mode conversion command, wherein the mode conversion command received by the primary module includes:
- an enter_partial_mode command to indicate that the display module enters a partial driving mode, or
- an enter_normal_mode command to indicate that the display module enters an entire driving mode.
