The present application relates to light-emitting diode (LED) driver circuits, display devices, and display systems. An example LED driver circuit includes: a driver including a plurality of data channels; a controller electrically connected to the driver. The controller is configured to, in response to detecting that data in all the data channels isin a predetermined time period, control all the data channels to be in a closed state. The predetermined time period is determined based on a duration of an external input signal input to the LED driver circuit.

LED driver circuit, display device, and display system

A laser annealing apparatus, a fabrication method of a polysilicon thin film, and a fabrication method of a thin film transistor are provided. The laser annealing apparatus includes: a laser generator, an optical system and an annealing chamber. The laser generator is configured to emit a laser beam, and the laser beam is guided to the annealing chamber via the optical system. The optical system includes a beam splitter, the beam splitter decomposes the laser beam into a first beam and a second beam, an energy density of the first beam is greater than an energy density of the second beam, and the first beam and the second beam are guided into the annealing chamber for laser annealing.

Laser annealing apparatus, and fabrication methods of polycrystalline silicon thin film and thin film transistor

A laser annealing apparatus including a carrying platform with a fixing surface, a laser source and a driving device. The laser source is configured to emit a laser beam toward the fixing surface, the laser beam having an illumination area which covers a center of the fixing surface and extends toward an edge of the fixing surface, in an extending direction of the illumination area the illumination area having a length which is not less than a distance between the center of the fixing surface and the edge of the fixing surface. The driving device is configured to drive the carrying platform to rotate around the center of the fixing surface.

Laser annealing apparatus and laser annealing method for substrate

An excimer laser generator and an excimer laser annealing equipment are disclosed to improve the convenience of window replacement, improve the replacement efficiency and reduce the gas waste. The excimer laser generator includes a reflector, an active medium cavity and an output mirror arranged in sequence. The active medium cavity has a first opening facing the reflector and a second opening facing the output mirror. The excimer laser generator further includes two replacement units respectively arranged between the first opening and the reflector, and between the second opening and the output mirror. Each of the replacement units includes a support plate and a driving component. The support plate is provided with a plurality of windows, and the driving component is adapted for driving the support plate so that one of the plurality of windows seals a corresponding opening.
