  • Patent number: 11249590
    Abstract: This application is directed to intra-panel communication in a touch display device in which a touch-integrated timing controller (TTCON) is coupled to touch-embedded source drivers (TSDs) via a plurality of forward links and a set of backward links. The forward links include a first subset of display forward links and a second subset of touch forward links. The TSDs are electrically coupled to a display panel including a plurality of display pixels and a plurality of touch sensors. The TTCON sends a display drive signal including display content data and display control data over the display forward links, and sends a touch control signal including an instruction to initiate an operation mode over the touch forward links. Upon receiving the touch control signal, the TSDs identify the instruction to initiate the operation mode, generate touch data accordingly, and return the touch data to the TTCON via the backward links.

  • Patent number: 10540314
    Abstract: A protocol transparent retimer circuit monitors certain link layer control signals, detects far-end receiver parameters of the link partners, and detects attributes of the data signal on the link to determine the link status and operate the retimer in accordance with the determined link status. By combining and reducing host and device system states into a few retimer states, the retimer circuit is largely simplified and yet still serves its purpose. The retimer includes a controller that employs a state machine to interpret the monitored and detected signals to determine the link state and operate the retimer in an operational state corresponding to the determined link state. The approach enables the retimer to restore signal integrity and forward data it receives in both downstream and upstream directions of the link without frequency alteration.

  • Patent number: 9935839
    Abstract: A source device communicates with a sink device over a main communication channel and configuration data is sent over a display data channel. A retimer is coupled between the source device and the sink device to improve the quality of signal transmitted from the source device to the sink device. The retimer monitors the data being sent on the display data channel to look for a desired command. Once the command is found, a copy of the command is decoded by the retimer and the configuration data and associated values are stored in a storage. The retimer uses the stored configuration data to modify the received communication data signal to match the operational characteristics between the source device and sink device and then transmit the modified signal to the sink device using these operational characteristics.

  • Patent number: 9659538
    Abstract: A system and method are disclosed to control the power consumption of column drivers in a display system. A video input signal is received which has an active video period and a vertical blanking period between frames. A timing controller transmits a first video frame to a column driver. The timing controller transmits a column driver disable command during a vertical blanking period. Prior to the subsequent active video period, the timing controller transmits a column driver enable command. The timing controller proceeds to transmit a second video frame to the column driver. In one embodiment, the timing controller determines whether to disable and enable the column driver based on a refresh rate, the refresh rate calculated by the timing controller from the video input signal.

  • Patent number: 9106770
    Abstract: A system and method are disclosed for embedding a timing controller on column drivers which, among other advantages, reduces power consumption and size constraints. A standalone timing controller is eliminated by splitting a video input signal and delivering the signal to each of the column drivers. Timing controller functionality is embedded in each of the column drivers to allow the column drivers to process the received video signal. An auxiliary input used for communication between column drivers and an external system is received by a master column driver. The master column driver communicates with slave column drivers to enable point to point communication between each column driver and the external system.

  • Patent number: 9100555
    Abstract: A system and a method are disclosed for a hybrid mode re-driver which, among other advantages, reduces power consumption while maintaining signal integrity. Equalization is performed on a signal to remove distortions such as inter-symbol interference. The signal is then analyzed and the quality of the signal is assessed. In some cases, retiming is then performed on the signal to remove additional signal distortions. In other cases, retiming is not performed and is transmitted to a driver while bypassing retiming components. When retiming components are bypassed, the retiming components are placed in a state of reduced power consumption to reduce system power consumption.
