Problems solved by technology
For flexible OLED (Organic Light-Emitting Diode) displays, because of the need to compensate the threshold voltage (Vth) of thin film transistors and the mobility of electron holes in the film, more Gate signals are required. In this way, Gate signals are provided from an external IC. signal becomes very difficult

Embodiment Construction
[0026] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0027] The realization of the mass production of GOA (GateDriverOnArray, array substrate row drive) technology is to use GOA technology to integrate the gate switch circuit on the array substrate of the display panel, so that the gate drive integrated circuit part can be saved, and the cost of materials can be reduced. and production process to reduce product costs. The gate switching circuit integrated on the array substrate using GOA technology is also called GOA circuit. The invention relates to a GOA shift register circuit of a full PMOS (positive channel Metal Oxide Semiconductor, p-channel Metal Oxide Semiconductor Field Effect) transistor.
[0028] Please see figure 1 and figure 2 As shown, in the first embodiment of the present invention, all transistors of the present invention are PMOS transistors, and t...

The invention discloses a shift register circuit, which is used to connect with a pixel compensation circuit corresponding to a GOA unit, which includes: an input module, the input module is connected to a signal input terminal, and the input module is used to input The input signal provided by the end generates an output control signal; a shift register module, the shift register module is connected to the input module, and the shift register module is used to invert the output control signal to output a light-emitting signal to The pixel compensation circuit corresponding to the GOA unit; the shift register module includes a first capacitor, a second capacitor, a first transistor, a second transistor, a third transistor and a fourth transistor. The shift register circuit of the present invention requires a small number of thin film transistors (TFTs), and the transistors are all PMOS designs, which can save manufacturing processes and improve production efficiency. The invention also provides a shift register unit.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a shift register circuit and a shift register unit using the shift register circuit. Background technique [0002] The Gate Driver On Array (GOA for short) technology is to use the existing thin-film transistor display array (Array) process to manufacture the gate (Gate) row scanning drive signal circuit on the array substrate to realize the gate driver on array. A technology of the driving method of line scanning. Among them, the GOA technology is also called a shift register technology. GOA technology allows the Gate circuit to be integrated on the panel (panel), which can save the driver IC (Integrated Circuit) that provides the Gate potential signal. For flexible OLED (Organic Light-Emitting Diode) displays, because of the need to compensate the threshold voltage (Vth) of thin film transistors and the mobility of electron holes in the film, more Gate signals are required. ...
