Abstract: A display device is provided. A data line includes a main line section, a first line section and a second line section spaced apart from one another. The first and second line sections respectively cross over a first scan line set to form first and second crossing regions. The main line section crosses over a second scan line set to form third crossing regions. The first line section is electrically connected to the main line section and one scan line of a third scan line set via a first switch element. The second line section is electrically connected to the main line section and another scan line of the third scan line set via a second switch element.

Abstract: A bi-directional optical module includes a substrate, at least one first light-emitting diode (LED), and at least one second LED. The first LED is disposed on a surface of the substrate. The first LED has a first reflection surface and a first light-outlet surface that are opposite to each other, and the first light-outlet surface is away from the substrate relative to the first reflection surface. The second LED is disposed on the same surface of the substrate. The second LED has a second reflection surface and a second light-outlet surface that are opposite to each other, and the second light-outlet surface is close to the substrate relative to the second reflection surface. The substrate has at least one light-transparent area that is not occupied by the first LED and the second LED.

Abstract: A light-emitting diode display device and a light-emission control method thereof are provided. The light-emitting diode display device includes a timing controller, multiple display pixels, and a scanning circuit. The display pixels form multiple display rows. The scanning circuit generates multiple scan signals and multiple light-emission signals that respectively drive the display rows. During a first data-writing time period of a first frame period, the timing controller provides multiple writing data to be respectively written into the display rows. During a light-emitting time period, the scanning circuit drives each of the light-emission signals to generate multiple pulses periodically according to a set period to drive the corresponding display rows. The light-emitting time period is after the first data-writing time period and before a second data-writing time period of a second frame period ends.

Abstract: The disclosure provides a pixel circuit including a lighting element, a current source, an amplitude control circuit, a pulse width control circuit, and an internal compensation circuit. The current source includes a driving transistor, and provides a driving current to the lighting element by the driving transistor. The amplitude control circuit includes a first switch, and provides a first voltage to the driving transistor by the first switch to determine magnitude of the driving current. The pulse width control circuit provides a second voltage to the first switch to determine a pulse width of the driving current. The internal compensation circuit is coupled with the current source and the amplitude control circuit, detects a threshold voltage of the first switch, and provides the driving current to an external compensation circuit to render the external compensation circuit detect a threshold voltage of the driving transistor.
