Abstract
The present application discloses a display substrate, a preparation method thereof, and a display device. The display substrate includes: a substrate, a driving structure layer including a thin film transistor disposed on the substrate, and an auxiliary electrode layer disposed on the driving structure layer , the first electrode and the pixel defining layer are sequentially arranged on the auxiliary electrode layer, wherein the auxiliary electrode layer includes a connecting electrode, a first auxiliary wiring and a second auxiliary wiring, and the first electrode is electrically connected through the connecting electrode to the source or drain of the thin film transistor, wherein the first auxiliary wiring and the second auxiliary wiring are located at the edge of the orthographic projection of the opening area defined by the pixel defining layer, and are perpendicular to the display substrate On a plane, a cross section of the first auxiliary wiring and a cross section of the second auxiliary wiring are symmetrical to the center line of the opening area defined by the pixel defining layer. In the display substrate provided in this embodiment, symmetrical auxiliary wirings are arranged so that the first electrodes protrude symmetrically, thereby improving color shift.
Description
A display substrate, its preparation method, and display device technical field [0001] The present application relates to display technology, in particular to a display substrate, a method for preparing the same, and a display device. Background technique [0002] Since the current market has the characteristics of curling, wide viewing angle, and easy portability for flexible display devices, portable products should be used in portable products. It has a wide range of applications, its prospects and good market potential. [0003] Flexible OLED (Organic Light-Emitting Diode, organic light-emitting diode) products due to its higher The advantages of color saturation, large viewing angle, high contrast, and fast response time are now widely used in mobile phones, notebooks etc. products. As the screen size increases, dual SD (SD1 and SD2) designs are often used to reduce the voltage drop in the traces, since SD2 Due to the influence of thickness, there are often probl...
