Problems solved by technology

[0005] Organic electroluminescent displays emit light through multiple sub-pixels with different colors of outgoing light, and each sub-pixel needs to be driven by a corresponding pixel circuit to achieve light emission. Therefore, an organic electroluminescent display will have tens of thousands or even There are millions of pixel circuits, how to effectively test these pixel circuits is a big project, and the current testing technology is not convenient enough

Abstract

The invention discloses an array substrate, testing, forming method, device and display panel forming method. The array substrate includes a substrate, a plurality of pixel circuits on the substrate, and a plurality of test patterns corresponding to the plurality of pixel circuits. The pixel circuit includes a driving unit, and the test The pattern is electrically connected to the driving unit, and the test pattern is used to output a test signal flowing through the driving unit. The present invention can obtain the test signal through the test pattern arranged on the array substrate, and the test signal can be used to detect whether there is a defect in the pixel circuit, and the detection process is simple and convenient.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a testing and forming method, a device, and a display panel forming method. Background technique [0002] Today, with the development of multimedia technology and the advent of the information society, the requirements for electronic equipment are getting higher and higher, such as display equipment, communication equipment and so on. [0003] Taking display equipment as an example, in recent years, three new display technologies have emerged: plasma display, field emission display and organic electroluminescent display, all of which have made up for the shortcomings of cathode ray tubes and liquid crystal displays to a certain extent. [0004] Among them, Organic Light Emitting Devices (OLED) has a series of advantages such as self-luminescence, low-voltage DC drive, full curing, wide viewing angle, and rich colors. Compared with liquid crystal displ...
