Problems solved by technology

[0003] As the resolution of the display device becomes higher and higher, the number and difficulty of wiring of the data lines increase accordingly, and the increase in the number of wiring of the data lines results in a larger width of the frame when the AMOLED panel is applied to the display device. , and this does not conform to the current trend of narrow borders, and the increase in the number of data line wiring also increases the difficulty of the manufacturing process of AMOLED display panels, reducing the manufacturing yield of AMOLED display panels

Abstract

The invention relates to the display technical field and particularly relates to an AMOLED display panel and an organic light emitting display device. The display panel comprises a pixel circuit, data lines coupled to the pixel circuit, a drive chip, a multi-way selection unit and a voltage stabilization unit. The drive chip is used for providing a first data signal, the multi-way selection unit is connected between the data lines and the drive chip to transmit the first data signal to the data lines, and the voltage stabilization unit is connected between the data lines and the drive chip to output a second data signal to the data lines. The data lines receive the second data signal provided by the voltage stabilization unit before the data writing-in stage. By means of the display panel and the organic light emitting display device, the voltage stabilization unit is used, so that the multi-way selection unit can be used; the arranging number of the data lines in the display panel is reduced due to the usage of the multi-way selection unit, and accordingly, the size of the display panel is reduced, and the fabrication process difficulty is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an AMOLED display panel and an organic light-emitting display device. Background technique [0002] With the development of display technology, the application of Active Matrix / Organic Light Emitting Diode (AMOLED for short), which is called the next generation display technology, is becoming more and more important. The light-emitting device of the AMOLED is an organic light-emitting diode (Organic Light-Emitting Diode, hereinafter referred to as OLED), driven by the AMOLED driving circuit, when a current flows through the light-emitting device OLED, the OLED emits light. [0003] As the resolution of the display device becomes higher and higher, the number and difficulty of wiring of the data lines increase accordingly, and the increase in the number of wiring of the data lines results in a larger width of the frame when the AMOLED panel is applied to the display device. , an...
