  • Patent number: 11908433
    Abstract: A display device includes: a pixel part partitioned into blocks; a scale factor provider which calculates a first load value of input image data for the pixel part, calculates a second load value of the input image data for each block, and generates a scale factor based on the first and second load values; and a timing controller which generates image data by scaling gray values of the input image data based on the scale factor. The scale factor provider generates a first scale factor for commonly controlling the gray values for the blocks based on the first load value, when the first load value is greater than or equal to a reference load value, and generates a second scale factor for controlling gray value for each block based on the first and second load values, when the first load value is less than the reference load value.

  • Patent number: 11888472
    Abstract: Example systems described herein are configured to limit inadvertent actuations of a touchpad. The system may include a touchpad, mechanically-activated switch(es), a locking assembly, and a controller. The touchpad is configured to receive a touch input from a user. The mechanically-activated switch(es) are adjacent to the touchpad.

  • Patent number: 11749225
    Abstract: A unit circuit constituting each stage of a shift register serving as a gate driver of a display device charges an internal node to an H level via a transistor T2 when an output signal G(n?4) of a preceding stage turns to the H level and sets the internal node to an L level via a transistor T3 when an output signal G(n+8) of a succeeding stage turns to the H level. Each of the unit circuits of last eight stages in the gate driver is provided with a transistor T4 including a gate terminal to which the signal G(n?4) is applied and a drain terminal connected to the internal node. A signal is applied to a source terminal of the transistor T4, the signal being at the H level during a period when the internal node of any of the last eight stages is to be set to the H level, and being the L level during the other periods. This suppresses a voltage fluctuation generated in the internal node when a stabilization circuit does not normally function.
