  • Patent number: 11262876
    Abstract: An electronic device, a touch detection circuit and an update method for a reference value of a touch screen are provided. The update method includes: acquiring a temperature value of an environment of the touch screen; when determining that the acquired temperature value is less than a preset temperature threshold and determining that a continuously touched area exists in the touch screen, collecting N data frames of the continuously touched area; calculating N feature values of the N data frames; and updating N reference values corresponding to the N data frames according to the N feature values; wherein, N is greater than 1 and N is an integer. A difference between a reference value and a sensed value of the continuously touched area may not be decreased with a temperature rise due to the heat transferred by a touched object, thus point elimination at a low temperature is avoided.

  • Patent number: 10042484
    Abstract: A touch screen is disclosed. In some examples, the touch screen comprises a touch sensor panel including a plurality of touch pixels that include a first and a second touch pixel, a first sense connection coupled to the first touch pixel, and a second sense connection coupled to the second touch pixel. In some examples, a touch controller is configured to detect an object coupled to the first touch pixel and the second sense connection, and in response to detecting the object, output substantially no touch signal associated with the second touch pixel. In some examples, the touch controller is further configured to scale a first touch signal associated with the first touch pixel by a first correction coefficient corresponding to the first touch pixel and the second touch pixel, and subtract the scaled first touch signal from a second touch signal associated with the second touch pixel.

  • Patent number: 10007386
    Abstract: A mobile terminal device receives an input of a pressing operation when an operation surface is pressed. A pressing amount detecting unit detects whether or not the operation surface has been pressed. A grip determining unit determines whether or not the housing has been gripped by a user. A threshold adjusting unit adjusts a press detection sensitivity of the pressing amount detecting unit when the housing is gripped by the user and when the housing is not gripped by the user. By this means, it is possible to provide an input device which adequately detects a pressing operation, and a program which is executed by this input device.

  • Patent number: 9753574
    Abstract: In one embodiment, logic embodied in a computer-readable non-transitory storage medium of a device determines a location of a touch gesture by a user within a touch-sensitive area of the device. The logic selects for the touch gesture based on its location within the touch-sensitive area one of a plurality of pre-determined offsets, the pre-determined offsets being specific to the device, the pre-determined offsets being derived from device-specific empirical data on usage of the device by a plurality of users, and the pre-determined offsets being pre-loaded onto the device. The logic applies the pre-determined offset to the location of the touch gesture to determine a touch input intended by the user.
