Abstract: Disclosed are a touch circuit and driving method, and a touch display panel, the touch circuit includes a plurality of touch units, each touch unit includes a touch signal line, one or more data lines corresponding to the touch signal line, a data signal line connected to the data lines, transmitting a data signal to the data lines, a common signal line connected to the touch electrode; each touch unit includes a first transistor, a control terminal of the first transistor is connected to a first control signal line, a first conducting terminal is connected to the data lines or the data signal line, a second conducting terminal is connected to the touch signal line; though the aforesaid structure, reusing of the data signal line, reducing of the number of wires in the fanout wiring area, an effect of narrow bezel in the lower bezel can be realized.

Abstract: This application discloses a display panel and a display device. There is a fingerprint recognition region in the display area. A fingerprint recognition element is disposed in the display panel correspondingly below the fingerprint recognition region. The display panel includes an organic light-emitting layer and a color filter layer arranged on a light-emitting side of the light-emitting layer. The color filter layer includes a first black matrix and a color filter. The first black matrix is disposed corresponding to the fingerprint recognition region. Adjacent color filters are separated by the first black matrix. The first black matrix includes carbon black filaments, which are in the shape of elongated strips. Each carbon black filament has a length that lies in the range of 100 nm to 1000 nm and a diameter range that lies in the range of 1 nm to 100 nm.

Abstract: Some embodiments of the present disclosure provide an array substrate and a display pane. Multiple pixel electrode branches in a corresponding one of the pixel regions are divided into a first pixel electrode branch and a second pixel electrode branch by a corresponding one of the metal common electrodes. The first pixel electrode branch and the second pixel electrode branch, which are located in different pixel regions and which are adjacent to each other, are respectively connected to different drains of the same TFT. In each pixel region, an end of the first pixel electrode branch close to a corresponding one of the scan lines is connected to a corresponding one of the TFTs, and an end of the second pixel electrode branch close to another corresponding one of the scan lines is connected to another corresponding one of the TFTs.

Abstract: Examples of performing selective Fine Timing Measurement (FTM) are described. For an FTM scan cycle, a first AP (i.e., an initiator) may determine scanning parameter values of a plurality of second APs (i.e., potential responders) based on previously performed FTM scans. The first AP may determine weights of the plurality of second APs based on the scanning parameter values and select a set of target APs based on the weights. The first AP may then scan the set of target APs for the FTM scan so that the rest of the plurality of second APs are relieved from participating in the FTM scan thereby reducing the performance impact on the rest of the plurality of second APs. After the FTM scan cycle is completed, the first AP may update the weights and select another set of target APs based on the updated weights to perform another FTM scan cycle.
