  • Patent number: 11922887
    Abstract: A display may include an array of pixels. Each pixel in the array includes an organic light-emitting diode coupled to associated thin-film transistors. The diode may be coupled to drive transistor circuitry, a data loading transistor, and emission transistors. The drive transistor circuitry may include at least two transistor portions connected in series. The data loading transistor has a drain region connected to a data line and a source region connected directly to the drive transistor circuitry. The data line may be connected to and overlap the drain region of the data loading transistor. The data line and the source region of the data loading transistor are non-overlapping to reduce row-to-row crosstalk.

  • Patent number: 11198770
    Abstract: The present disclosure relates to an interlayer film for laminated glass comprising: (a) polyvinyl butyral (PVB) resin having an average molecular weight (Mw) as measured by Gel Permeation Chromatography (GPC) from about 175,000 to about 210,000 Dalton; and (b) about 30 to about 50 parts per hundred (pph) of a plasticizer. The interlayer film interposed between two glass sheets forms laminated glass having a pummel adhesion value that is greater in an outer area of the laminated glass than in a middle area of the laminated glass after the laminated glass has been maintained at 50° C. and 95% relative humidity (RH) for 28 days. The laminated glass exhibits improved durability and does not delaminate over time, even in the presence of high temperature and humidity conditions.

  • Patent number: 10438575
    Abstract: The present invention relates to a multilayer film. In various embodiments the multilayer film is an interlayer film for laminated glass. The present invention also relates to an interlayer film for laminated glass, wherein the laminated glass has excellent sound insulating properties. The present invention also relates to a laminated glass that is obtained using this interlayer film. The present invention can effectively improve the compatibility of the resin film (B) with the plasticizer so that the intermediate layer (i.e., the resin film (B)) allows to add more plasticizer(s) to achieve the effect of enhancing sound-insulating. Furthermore, the intermediate layer of the multilayer film uses different plasticizer from the non-intermediate layer of the multilayer film so as to prevent the migration of plasticizers between different layers and the multilayer film has little or no plasticizer bleed-out.
