  • Publication number: 20240143114
    Abstract: A driving circuit includes: a display driver to generate a horizontal synchronization signal and a vertical synchronization signal according to a first clock signal of a first oscillator; a sensor driver to generate a touch signal according to a second clock signal of a second oscillator; and a determination circuit to detect a cycle of at least one of the horizontal synchronization signal or the vertical synchronization signal according to the second clock signal, and output a detection signal when the cycle is out of a range. The determination circuit is a part of the display driver or the sensor driver.

  • Publication number: 20240121998
    Abstract: A thin-film transistor including an active layer disposed on a substrate and including a channel region, a source region connected to a side of the channel region, and a drain region connected to the other side of the channel region; a gate insulating layer on the channel region of the active layer; and a gate electrode on the gate insulating layer. A slope of each side surface of the gate electrode with respect to a boundary surface between the gate insulating layer and the gate electrode is an obtuse angle (a substantially obtuse angel). A slope of each side surface of the gate insulating layer with respect to the boundary surface between the gate insulating layer and the gate electrode is an obtuse angle (a substantially obtuse angel).

  • Patent number: 11164390
    Abstract: A user wears a virtual reality mask (VR mask) (100) and then watches a virtual reality image. The VR mask (100) blocks light incident from the outside. When the user wears the VR mask (100), the user cannot discover an obstacle (500) positioned outside the VR mask (100). The user may collide with the obstacle (500) and may be injured by the obstacle (500). Accordingly, in order to prevent injury to the user who uses the VR mask (100), it is necessary to make the user recognize the obstacle (500) positioned outside the VR mask (100). In order to recognize an obstacle, a virtual reality image and the obstacle may be displayed together, or the amount of light incident from the outside may be adjusted.
