  • Publication number: 20240331622
    Abstract: A display device includes a display panel. The display panel includes sub-pixels. A driver converts first frame data corresponding to a first pixel arrangement of the sub-pixels into second frame data corresponding to a second pixel arrangement and provides data signals corresponding to second frame data to the sub-pixels having the second pixel arrangement. The driver includes a padding circuit and a rendering circuit. The padding circuit converts the first frame data into padding data by adding a padding value to at least one of a front end and a rear end of each line data of the first frame data. The rendering circuit generates the second frame data by applying a rendering filter to the padding data.

  • Patent number: 11629073
    Abstract: The present invention relates to a hybrid system for water treatment, desalination, and chemical production. The hybrid system of the present invention includes a photoanode, an anode chamber, an anion exchange membrane, a middle chamber, a cation exchange membrane, a cathode chamber, and a cathode. In the middle chamber, saltwater or seawater is desalinated by photoelectrochemical electrodialysis. Chloride ions are generated during the desalination, transferred to the anode chamber, and activated by the photoanode. In the anode chamber, wastewater is treated by the activated chloride ions. In the cathode chamber, at least one chemical species selected from the group consisting of water, oxygen, and carbon dioxide is reduced by electrons supplied from the photoanode.
