Abstract

The invention provides a display panel, a manufacturing method and a mobile terminal. The display panel comprises a substrate and a light-emitting driving layer located on the substrate. The light-emitting driving layer comprises a light-emitting device which is arranged on the substrate, wherein the light-emitting device comprises a light-emitting layer made of a semiconductor material, and a source electrode and a drain electrode which are positioned on two sides of the light-emitting layer; and a gate electrode which is located on at least one side of the light-emitting device, wherein the gate electrode and the light-emitting device are arranged in an insulated mode. According to the invention, the thin film transistor for controlling the switch and the light emitting structure of the light emitting diode are integrated to form the light emitting thin film transistor with the switch function, so the step of chip transfer can be omitted, and the problem of limitation of the chip transfer technology on the Mini LED / Micro-LED display panel at the present stage is relieved or greatly relieved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a manufacturing method and a mobile terminal. Background technique [0002] As the high-end TV market has higher and higher requirements for image quality, improving display image quality has become a new demand for high-end TVs. At present, Mini LED / Micro-LED, as a new display technology, has advantages over OLED in terms of brightness and power consumption, and has become a popular direction in the display field. [0003] However, as the size of Mini LED / Micro-LED becomes smaller and smaller, the difficulty of LED chip transfer process becomes more and more difficult, and when it reaches the level of Micro-LED, the traditional die-bonding process can no longer meet the needs of chip transfer. The transfer technology is not yet mature, so the chip transfer technology has become a key factor limiting the development of Micro-LED. Contents of the inv...
