Embodiment Construction
[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0039] As mentioned in the background technology, the existing silicon-based OLED products are seriously affected by particles, and there are technical problems such as abnormal yield rate and packaging failure. After careful research, the inventor found that the reason for this technical problem is that figure 1 is a schematic diagram of the position of the particle existing area in the prior art, see figure 1 , in the existing silicon-based OLED production process, the particles produced by evaporation account f...

The embodiment of the invention discloses a silicon-based OLED (Organic Light Emitting Diode) display substrate. The silicon-based OLED display substrate comprises a wafer substrate and a plurality of support isolation parts, wherein the wafer substrate comprises a substrate and a plurality of bare chips formed on the substrate; the plurality of supporting and isolating parts are located between adjacent bare chips on the wafer substrate, the height of the supporting and isolating parts is larger than that of the bare chips, and the supporting and isolating part strips are used for supporting the universal mask plate for evaporation. According to the embodiment, the technical problems that an existing silicon-based OLED product is seriously influenced by particles, the yield is abnormal and packaging fails are solved, in the evaporation process of the white light OLED device, the mask and the substrate are effectively isolated, particles remaining on the mask after cleaning are prevented from being attached to the substrate, the number of particles introduced into the silicon-based OLED product by the mask is reduced, and the production efficiency is improved. The yield of silicon-based OLED products is improved, and the risk of packaging failure is avoided.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a silicon-based OLED display substrate. Background technique [0002] With the rise of VR technology, VR products have increasingly stringent requirements on the pixel density of display devices, generally requiring a pixel density higher than 2000PPI, while traditional LCD and OLED technologies are difficult to manufacture display devices with higher pixel density. [0003] At present, most of the display devices used in VR products are silicon-based OLEDs. One of the ways to realize the colorization of silicon-based OLEDs is to prepare white OLED devices and perform colorization through color filters. Among them, the white OLED device usually adopts evaporation method to evaporate organic materials onto the substrate to realize light emission. [0004] Different from the preparation process of mobile phone display screens, evaporation white OLED devi...
