Abstract

The invention relates to rapid detection of performance of an OLED micro display, and particularly relates to a detection device and method for rapidly detecting OLED performance parameters in a high-temperature and high-humidity environment. The invention especially relates to a detection device and a rapid detection method. The detection device and the rapid detection method are used for realizing rapid detection of brightness uniformity, pixel defects and the like of an OLED micro display based on a digital visual reading system through a high-precision linear guide rail, a large-view-fieldmicroscope objective, a luminance meter, an image sensor and a software algorithm.

Description

technical field [0001] The invention relates to fast detection of the performance of OLED microdisplays, in particular to a device and method for fast detection of OLED performance parameters in a high-temperature and high-humidity environment. Background technique [0002] OLED is a device that converts electrical energy into light energy by driving the transport and recombination of carriers in organic materials by an external electric field. OLED microdisplays have low driving voltage, high luminous brightness, and wide operating temperature range (-40 to 80 ℃), wide viewing angle, fast response, simple manufacturing process, low cost and other advantages, has become the most promising, new type of flat panel display. [0003] Pixel defects and brightness uniformity of OLED microdisplays are important performance parameters of OLED microdisplays. Because OLED microdisplays are small in size and high in resolution, the commonly used methods for detecting pixel defects and ...
