A semiconductor processing apparatus includes a process chamber, a gas intake device, a base, and a flow guide structure. The process chamber includes a process area and a transfer area arranged from top to bottom, the gas intake device is disposed at a top of the process chamber for introducing a process gas into the process area. The base is vertically movable and is disposed in the transfer area for carrying a wafer. The flow guide structure is connected to a gas supply source, and fixedly attached to the base; and when the base is located at a process position, the flow guide structure is configured to blow a gas outward to an outer peripheral surface. An exhaust structure is disposed at the sidewall of the process chamber and is configured to discharge the gas blown out of the flow guide structure when the base is located at the process position.

Semiconductor processing apparatus

A driving method of a display panel includes: determining a brightness band of the display panel, wherein brightness bands include a first brightness band to an Nbrightness band, maximum grayscale brightness of the first brightness band to the Nbrightness band decreases sequentially, and each brightness band includes three Gamma correction curves respectively corresponding to a first light emitting unit, a second light emitting unit, and a third light emitting unit each of an (N&#x2212;M)brightness band to the Nbrightness band also corresponds to at least one duty ratio; determining an input data voltage corresponding to at least one light emitting unit based on a Gamma correction curve that corresponds to the determined brightness band and an image to be displayed; and driving the display panel to display the image based on the determined input data voltage, or the determined input data voltage and the duty ratio.

Display panel, driving method therefor, and display device

A driving method includes, at a first display brightness value, inputting a pulse-width modulation signal with a duty ratio of X, and controlling a light-emitting driving current of a sub-pixel unit to be M, wherein X and M are obtained according to a first modulation rule; and at a second display brightness value, inputting the pulse-width modulation signal with a duty ratio of Y1, and controlling the light-emitting driving current of the sub-pixel unit to be N1, wherein the first display brightness value is greater than the second one, wherein, when the duty ratio and the light-emitting driving current corresponding to the second display brightness value are obtained according to the first modulation rule, the duty ratio corresponding to the second display brightness value is Y2, the light-emitting driving current corresponding to the second display brightness value is N2, Y1 is smaller than Y2, and N1 is greater than N2.

Display panel, method of driving the same and display device

The present disclosure relates to a display substrate, a method for preparing the same, and a display device. The display substrate of the present disclosure includes a base substrate, a pixel definition layer located on the base substrate, and a first pixel and a second pixel that are adjacent to each other and defined by the pixel definition layer, in which a spacer function layer for blocking hole transport between adjacent pixels is arranged at at least a part of a contact interface between the second hole transport layer in the second pixel and the light function layer in the first pixel. By providing the spacer function layer, the present disclosure effectively prevents the migration of holes between the hole transport layers of adjacent pixels or between the hole transport layer and the light emitting layer, thereby avoiding accompanying light emission between adjacent pixels.
