    摘要： A display panel includes: a first display region; a component region surrounded by the first display region, wherein the component region includes at least one transmission region and at least one second display region surrounding the transmission region; one or more first sub-pixels disposed in the first display region; one or more second sub-pixels disposed in the second display region; a black matrix layer disposed in the first and second display regions and comprising a first opening overlapping the first sub-pixel in the first display region, a second opening overlapping the second sub-pixel in the second display region, and a third opening without overlapping the first pixel and the second pixel; and a touch wire disposed in the first display region and the second display region, and surrounding the first, second, and third openings.

    摘要： An OLED lighting device comprising: a blue light-emitting unit with a blue-light fluorescent, phosphorescent or TADF emitter; a yellow light-emitting electroluminescent unit comprising a green phosphorescent emitter, a red phosphorescent emitter and at least one non-emitting host; wherein the blue light-emitting unit and the yellow light-emitting unit are separated by a mixed interlayer with two non-emitting charge-carrier materials. Desirably, the yellow-light emitting unit essentially consists of a green phosphorescent emitter, a red phosphorescent emitter and a single non-emitting host. The mixed interlayer desirably has more than 50% of a hole-transporting material and an electron-transporting material. The Triplet Energy of both materials in the mixed interlayer can be higher than the Triplet Energies of the R and G phosphorescent dopants. The HOMOs of both materials in the mixed interlayer are more negative than the HOMO of the host in the yellow unit but less negative than the HOMO of the host in the blue unit. The LUMOs of the materials in the mixed interlayer can be more negative than the LUMO of the host in the yellow unit but less negative than the LUMO of the host in the blue unit. The OLED lighting device is spectrally tunable according to the supplied power.
