    摘要: A pressure sensor, a manufacturing method thereof, a pressure sensing method and a display device are provided. The pressure sensor includes a first electrode, at least two supports on a first surface of the first electrode, an elastic composite electrode on a side of the supports facing away from the first electrode. Two adjacent supports of the supports, the elastic composite electrode and the first electrode define a compressible space, and the at least two supports are formed of an insulating material. The pressure sensor further comprises a second electrode on a side of the elastic composite electrode facing away from the first electrode and an organic light emitting layer between the first electrode and the second electrode, the organic light emitting layer being in contact with one of the first electrode and the second electrode. The pressure sensor has advantages of low power consumption, fast response and high sensitivity.

    摘要: The present application relates to a pixel structure, a method for manufacturing the same, a display panel and a display device. The pixel structure includes a plurality of sub-pixels, each of which has a triangular shape. Sub-pixels of four different colors constitute a pixel unit. Any two sub-pixels that have the same common triangle edge have different colors. Each row and each column of sub-pixels are composed of alternately arranged upright triangle sub-pixels and inverted triangle sub-pixels. Every adjacent six columns of sub-pixels constitute a group. Each row of sub-pixels includes sub-pixels of four different colors, and each group of sub-pixels has the same arrangement. The upright triangle sub-pixels are sub-pixels of the other three different colors, and all of the inverted triangular sub-pixels are sub-pixels of the first color.

    摘要: A method of preparing organic functional layers of light-emitting device including: forming a plurality of holding portions in a pixel definition layer on a substrate; forming a plurality of ink droplets in the holding portions, the ink droplets including a first solvent, a second solvent and one or more solutes, a first saturated vapor pressure of the first solvent being higher than a second saturated vapor pressure of the second solvent, a solubility of the solutes in the first solvent being less than a solubility of the solutes in the second solvent, and a first affinity of lower parts of side walls of the holding portions for the first solvent is greater than a second affinity of the lower parts of the side walls of the holding portions for the second solvent; adjusting a vacuum degree of vacuum drying equipment to a first vacuum degree below the first saturated vapor pressure and above the second saturated vapor pressure to completely remove the first solvent; and adjusting the vacuum degree of the vacuum drying equipment to a second vacuum degree below the saturated vapor pressure of the second solvent to completely remove the second solvent.
