  • Patent number: 11586334
    Abstract: A display device includes a display portion, a display driver, a touch sensing portion, and a touch driver. The display portion includes data lines, scan lines, and pixels connected to the data lines and the scan lines. The display driver provides data signals to the data lines and sequentially provides scan signals to the scan lines. The touch sensing portion includes sensing electrodes. The touch driver senses a touch input based on a change of a capacitance between the sensing electrodes and calculates a movement speed of the touch input. When the movement speed of the touch input is greater than a reference speed, a first period in which the scan signals and the data signals are provided is reduced in a frame period in which a frame image is displayed.

  • Patent number: 10796616
    Abstract: An inspection system includes a display device including a nonvolatile memory, an inspection device configured to generate a writing voltage for application to the nonvolatile memory, and a protection part configured to apply the writing voltage to the nonvolatile memory when the writing voltage is within an allowable voltage range, and not to apply the writing voltage to the nonvolatile memory when the writing voltage is not within the allowable voltage range. The application of the writing voltage to the nonvolatile memory enables a multi-time programming (MTP) operation in which reference data writes to the nonvolatile memory.

  • Patent number: 9852018
    Abstract: A method of detecting an error of a multi-time programmable (MTP) operation in which each gamma-offset and each header-bit at predetermined reference gray-levels are written in a MTP memory device while the MTP operation is performed on a pixel circuit, the each header-bit indicating whether or not the each gamma-offset is written in the MTP memory device, and it is detected whether or not the MTP operation is performed on the pixel circuit based on a logical operation between the header-bits at the predetermined reference gray-levels read from the MTP memory device when the MTP operation is finished on the pixel circuit.
