Abstract

The present invention provides a display substrate and its detection method and detection device. The display substrate includes a display area and a peripheral area located around the display area. The display area is provided with display elements. The display substrate also includes a thin film encapsulation layer covering the display elements. The display substrate It also includes: a detection structure arranged in the peripheral area, the detection structure receives light and reflects the first light when it is not covered, the detection structure receives light and reflects the second light when at least a part of it is covered by the thin film encapsulation layer, the optics of the first light The parameters are different from the optical parameters of the second ray. According to the display substrate of the present invention, it can accurately detect whether the detection structure is covered, the detection efficiency is high, the detection result is reliable, the actual packaging reliability of the thin film packaging structure is ensured, and the influence caused by inaccurate detection is reduced. Through the detection method of the present invention And the detection device can accurately detect whether the organic material overflows, and the efficiency is high.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a detection method and a detection device thereof. Background technique [0002] At present, bendable displays can be realized through liquid crystal display (LCD) and organic light-emitting diode (OLED) display panels. Benefiting from the characteristics of self-illumination, OLED displays prepared on flexible substrates are easier to achieve bendable displays with smaller bending radii. Therefore, the fabrication of OLED display panels including flexible substrates has attracted extensive attention. Affected by the lightness, thinness and ease of bending of flexible displays, there are many new demands for flexible terminal equipment. The bending of flexible display products can be the bending of display components or the control circuit area of ​​display components. [0003] The most common packaging method for flexible displays is thin-film packaging, u...
