  • Publication number: 20240145644
    Abstract: A display substrate is provided. The display substrate includes a respective encapsulated unit and a separation structure substantially surrounding the respective encapsulated unit. The respective encapsulated unit includes a color conversion layer comprising one or more color conversion blocks; and a respective encapsulating block in an encapsulating layer encapsulating the one or more color conversion blocks. The encapsulating layer is at least partially absent in a peripheral region around the respective encapsulated unit.

  • Patent number: 11456818
    Abstract: The invention belongs to the field of low-power consumption Bluetooth technology in wireless communication, in particular to a method for improving the sensitivity of the receiver in a low-power consumption Bluetooth system. The method of the invention is to introduce a deinterleaver between the symbol pattern mapper and GFSK modulator of the transmitting terminal under the low-power consumption Bluetooth coding mode, which is used to perform additional processing on the bitstream data and then perform modulation; then, due to the introduction of interleaving, Turbo iterative processing of demodulation and decoding can be performed at the receiving terminal; the receiving terminal comprises a Turbo iterative demodulator and decoder, which is used to model the low-power consumption Bluetooth GFSK modulator and convolutional coder into finite state machines, and then combine the deinterleaver to use the BCJR algorithm for iterative demodulation and decoding.

  • Patent number: 11368194
    Abstract: The present disclosure provides an omnidirectional beamforming method. In the omnidirectional beamforming method, a space-time block coding is performed on a data stream to be sent to obtain the coded data stream. Omnidirectional beamforming matrices corresponding to a uniform rectangular antenna array are constructed. The beamforming is performed on the coded data stream through the omnidirectional beamforming matrices, to generate a signal to be sent of the uniform rectangular antenna array.
