The application discloses a display module, electronic equipment and a method for preparing the display module. The display module includes: a base layer; an inorganic layer, the inorganic layer is arranged on the base layer, and a first source and a first drain are arranged in the inorganic layer Pole, the first source and the first drain are used to connect with the IC terminal to form the first current loop; the first insulating layer, the first insulating layer is set on the inorganic layer, and the first insulating layer is provided with a polysilicon layer ; The second insulating layer, the second insulating layer is arranged on the inorganic layer, the gate layer is arranged in the second insulating layer; the flat layer, the flat layer is arranged on the second insulating layer, the second source and the second source are arranged in the flat layer The second drain, the second source and the second drain are used for wiring connection with the IC terminal to form a second current loop, and the first current loop and the second current loop form opposite compensations with respect to the IC terminal. The display module of the present application adopts a synchronous opposite compensation method, which can effectively improve the uniformity of compensation and ensure uniform brightness and uniformity of the display module.
Description
technical field [0001] The application belongs to the technical field of electronic equipment, and in particular relates to a display module, electronic equipment and a preparation method of the display module. Background technique [0002] At present, as consumers demand for large screens and high-definition electronic products, the number of devices in the screen of electronic products will increase. Therefore, when the screen of an electronic product is enlarged, IR drop (voltage attenuation) will occur at the power supply terminal of the OLED (Organic Light-Emitting Diode), which will cause the source-drain current to decrease exponentially and affect the brightness of the OLED panel and evenness. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a display module that can solve the problem in the prior art that the brightness and uniformity of the OLED panel is affected by the voltage attenuation at the power su...
