Samsung patents display system that checks for broken screen sections
Samsung has patented a method for managing large screens by dividing them into separate sections, each controlled by its own timing controller. These controllers are linked in a chain and can automatically determine which direction to send image data based on instructions from the main processor. The system also sends a status signal back to the processor if a section fails to receive data within a specific time limit.
In the filing’s own words
Disclosed are an electronic device and a controlling method of an electronic device. In particular, electronic device includes: a display panel divided into a plurality of regions; a panel driver configured to control driving of the display panel; a plurality of timing controllers configured to control the panel driver, each including two ports disposed in opposite directions, connected to each other through the two ports, and each corresponding to each of the plurality of regions; and a first processor configured to transmit a signal in a first direction through the plurality of timing controllers, wherein the plurality of timing controllers are configured to identify input/output directions of the two ports included in each of the plurality of timing controllers that correspond to the first direction in case of receiving a first signal including image data and a control instruction for transmitting the image data in the first direction from the first processor; and transmit the first signal in the first direction through the two ports included in each of the plurality of timing controllers and having the input/output directions identified as corresponding to the first direction. Various other embodiments are possible.
What exactly they claim (claim 1)
1. An electronic device comprising: a display panel comprising a plurality of regions; a panel driver comprising a plurality of driver circuits, wherein the panel driver is configured to control driving of the display panel; a plurality of timing controllers, wherein each timing controller of the plurality of timing controllers comprises two ports disposed in opposite directions, the plurality of timing controllers are connected to each other through the respective two ports, and each timing controller of the plurality of timing controllers corresponds to a region of the plurality of regions; memory storing instructions; and at least one processor configured to execute one or more of the instructions, wherein the one or more of the instructions, when executed by the at least one processor, cause the at least one processor to transmit a first signal in a first direction through the plurality of timing controllers, wherein the first signal comprises image data and a control instruction for transmitting the image data in the first direction, wherein the plurality of timing controllers are configured to execute one or more of the instructions, and wherein the one or more of the instructions, when executed by the plurality of timing controllers, cause the plurality of timing controllers to: based on receiving the first signal, identify an input/output direction of each of the two ports of each timing controller of the plurality of timing controllers corresponding to the first direction; configure the input/output direction of each of the two ports of each timing controller of the plurality of timing controllers to correspond to the identified input/output directions; transmit the first signal in the first direction through the two ports of each timing controller of the plurality of timing controllers; and transmit a state signal corresponding to a state of the display panel based on whether at least one of the plurality of timing controllers receives the first signal within a predetermined threshold time, wherein the state signal is transmitted from at least one of the plurality of timing controllers to the at least one processor.
