Abstract

The invention provides an analysis method and an analysis device for a blank screen of a display panel, and the method comprises the steps: obtaining an abnormal type of a to-be-detected display panel which is a display panel with a blank screen; if the abnormal type is short circuit, applying a detection voltage to a preset port of the to-be-detected display panel, so that the voltage difference between a positive power supply input pin and a negative power supply input pin of the to-be-detected display panel reaches a preset voltage difference, or enabling a voltage difference between a first end and a second end of a predetermined abnormal line of the to-be-detected display panel to reach a preset voltage difference; acquiring temperature distribution information of the to-be-detected display panel after the detection voltage is applied; and determining an abnormal heating position of the to-be-detected display panel according to the temperature distribution information. The analysis efficiency of the blank screen of the display panel is improved, and the analysis success rate is increased.

Description

technical field [0001] The present application relates to the field of analyzing display panels with abnormal displays, and in particular relates to an analysis method and an analysis device for a black screen of a display panel. Background technique [0002] With the development of optoelectronic and semiconductor technologies, Liquid Crystal Display (LCD) has become the mainstream of the market due to its high space utilization efficiency, low power consumption, no radiation, and low electromagnetic interference. In order to enhance people's visual effects and widen the viewing range, the liquid crystal displays on the existing market require narrower and narrower frame widths. Narrow bezel liquid crystal displays usually require a Gate Driver on Array (GOA) design, that is, directly designing electrode drive circuits on the array substrate, reducing manufacturing procedures, reducing product costs, and making panels thinner and lighter. [0003] However, the integration ...
