The present disclosure relates to a touch power management circuit and a touch driving system comprising the same, and more particularly, relates to a touch power management circuit to generate signals required for a touch driving by using voltage sources different in a pen touch driving period and a finger touch driving period in order to reduce power consumption of a display device and a touch driving system comprising the touch power management circuit.

The present disclosure relates to a technology for supplying power to a display device and provides a device which checks a control value for each mode stored in a memory according to a mode indication signal in a simple form received from an external device and controls operation states of power converting circuits in each mode according to the control value for each mode.

A power circuit according to the present disclosure may include a multiplexer connected to a first power line and a second power line and selecting and outputting one of a first voltage supplied through the first power line and a second voltage supplied through the second power line. Further, the power circuit may include a first power circuit which generates a first driving voltage and a second driving voltage by using a voltage supplied from the multiplexer, recognizes whether there is the first voltage supplied through the first power line, and does not output the first driving voltage when the first voltage is not recognized.

The invention relates to a system for recording a track comprising: a utensil comprising a tip and equipped with a magnetic object; a device for locating the magnetic object configured to determine an estimated reference position on a writing surface; and a matrix-array touch sensor configured to define a set of M pixels, among N pixels, at least partially encircling the estimated reference position, and to detect the contact of the tip on the writing surface on the basis of the electrical signals generated by said set of M pixels.

An electronic device, detects a touch input. After a latency period, the device delivers to an application a sequence of input events that represent the touch input, including, in sequence: a first input event that represents the touch input at a first input time and is delivered at a first delivery time, a second input event that represents the touch input at a second input time and is delivered at a second delivery time, and a third input event that represents the touch input at a third input time and is delivered at a third delivery time, a time interval between the second input time and the second delivery time is smaller than a time interval between the first input time and the first delivery time, and a time interval between the third input time and the third delivery time is smaller than the time interval between the second input time and the second delivery time.

A device that can autonomously scan a sensor panel is disclosed. Autonomous scanning can be performed by implementing channel scan logic. In one embodiment, channel scan logic carries out many of the functions that a processor would normally undertake, including generating timing sequences and obtaining result data; comparing scan result data against a threshold value (e.g., in an auto-scan mode); generating row count; selecting one or more scanning frequency bands; power management control; and performing an auto-scan routine in a low power mode.

A display device includes a display driving controller receiving input image data, a synchronization signal, and a voltage control signal, and generating image data based on the input image data and the synchronization signal, a display panel including pixels disposed on a display area and displaying an image on the display area based on the image data, and a touch sensor including sensing electrodes on a sensing area, and detecting a touch input generated in the sensing area by driving the sensing electrodes. The display driving controller generates a second level of the synchronization signal by changing a voltage level of the synchronization signal having a first level based on the voltage control signal, and provides the synchronization signal having the second level to the touch sensor. The touch sensor deactivates at least a partial area of the sensing area in response to the synchronization signal having the second level.

The present embodiment relates to a touch power management circuit and a touch driving system including the same, and more particularly, to a touch power management circuit that prevents unnecessary power consumption during a pen touch driving period in order to reduce power consumption of a display device, and a touch driving system including the same.

Computing devices and methods for determining opening and closing of touch sensitive interfaces are disclosed. In one example, a computing device comprises a touch screen display on a first substrate that is rotatably coupled to a second substrate that includes a trackpad. A trackpad identification signal transmitted by the trackpad is received at the touch screen display, and a touch screen identification signal transmitted by the touch screen is received at the trackpad. If the trackpad identification signal matches a trackpad identification key and the touch screen identification signal matches a touch screen identification key, then an energy level of one or both signals is compared to an energy level threshold. Based at least in part on the comparison of the energy level to the threshold, a power state transition is initiated.
