Abstract: The present disclosure provides a mask plate, an OLED display substrate and a method for manufacturing the OLED display substrate, and a display device. The mask plate comprises a plurality of openings arranged as an array and configured to prepare patterns of a pixel definition layer, wherein a width of the opening close to a first side of the mask plate in a first direction is greater than that of the opening away from the first side of the mask plate, and the first direction is a direction from the opening close to the first side of the mask plate to the opening away from the first side of the mask plate. A slope angle of the pattern of the pixel definition layer close to a second side of the OLED display substrate is smaller than that away from the second side of the OLED display substrate.

Abstract: Methods, systems, and devices are described for communicating data from multiple data terminals to an aggregator terminal over a communication link having changing link conditions. In some embodiments, source data is received at multiple data terminals, each in communication with an aggregator terminal over a communication link. For example, during a live newscast, one mobile camera may receive live video of an event from a first position while another mobile camera receives live video of the event from a second position. For various reasons (e.g., as the cameras move) each communication link may experience independently changing link conditions. Each data terminal encodes the source data (or store source data for later encoding) as a function of its respective link conditions, and transmits encoded source data over its respective communication link to the aggregator terminal.

Abstract: One example includes a digital signal conditioner (DSC) system. A sample selector bank receives a digital sample block of an input signal that is provided at a supported input oversampling factor and selects a subset of samples from the digital sample block based on a selection signal.

A filter bank receives the subset of the samples from each of the sample selectors and a respective set of tap weights. Each filter provides a weighted sample associated with the respective subset of samples and the respective set of tap weights. A reformattor receives the weighted sample from each of the filters and provides a filtered sample block including the weighted sample from a subset of the filters at an output oversampling factor for each supported input oversampling factor based on a selected supported resampling ratio.

The buffer can be configured to store the first digital sample blocks and the second digital sample blocks and to release the buffered first and the second digital sample blocks for flow downstream when the stream of first digital sample blocks and the stream of second digital sample blocks are aligned.
