AMOLED (active matrix organic light-emitting diode) panel pixel circuit layout and production method thereof

Abstract

The invention discloses an AMOLED (active matrix organic light-emitting diode) panel pixel circuit layout which comprises strip sub-pixels, a switch transistor T1, a driving transistor T2, a scanning line Vscan, a data line Vdata, a power line, a storage capacitor and an organic light emitting diode. The scanning line Vscan is distributed along the long edge of the strip sub-pixels in the pixel circuit layout, the data line Vdata is distributed along the short edge of the strip sub-pixels in the pixel circuit layout, and an organic material evaporation area of the organic light-emitting diode is widened along the short edge of the strip sub-pixels, and remains unchanged along the long edge. According to the characteristics, the organic material evaporation area of the sub-pixels can be widened, and aperture ratio of the panel is increased. According to a JVL (density-voltage-luminescence) curve characteristic of organic light-emitting materials, driving current density and driving voltage can be reduced by increasing the aperture ratio of the panel, so that service life of organic materials of the panel can be prolonged, power consumption of the organic materials of the panel can be reduced, and panel performance can be improved.

Description

Technical field [0001] The present invention relates to the field of AMOLED display technology, in particular to a layout of an AMOLED panel pixel circuit and a manufacturing method thereof. Background technique [0002] In flat panel display technology, Organic Light-Emitting Diode (OLED) displays have many advantages such as thinness, active light emission, fast response speed, wide viewing angle, rich colors and high brightness, low power consumption, high and low temperature resistance, etc. It is recognized by the industry as the third-generation display technology after the liquid crystal display (LCD). Active OLED (Active Matrix OLED, AMOLED) is also known as active matrix OLED. AMOLED integrates thin film transistors (TFT) and capacitors in each pixel and is driven by the capacitor to maintain the voltage, which can achieve large size and high resolution. The rate panel is the focus of current research and the development direction of future display technology. [0003] T...

Problems solved by technology

Moreover, in order to reduce the IR-DROP (resistance voltage drop) of the power line Vdd, it is generally necessary to design the power line Vdd to be much wider than the scan line Vscan of the data line Vdata, which further affects the pixel aperture ratio.
