Embodiment Construction

[0058]As used herein, "about," "approximately," "essentially," or "essentially" includes the stated value and the average within an acceptable range of deviation from the particular value as determined by one of ordinary skill in the art, taking into account the The measurement in question and the specific amount of error associated with the measurement (ie, limitations of the measurement system). For example, "about" can mean within one or more standard deviations of the stated value, or for example within ±30%, ±20%, ±15%, ±10%, ±5%. Furthermore, "about", "approximately", "essentially" or "substantially" used herein may select a more acceptable range of deviation or standard deviation according to measurement properties, cutting properties or other properties, and may not use One standard deviation applies to all properties.

[0059] In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. It will be understood that when an eleme...

Abstract

A display panel comprises a substrate, an isolation structure layer, a plurality of light-emitting elements, a plurality of wavelength conversion patterns and a filter layer. The isolation structure layer is arranged on the substrate and is provided with a plurality of first grooves and a plurality of second grooves which are alternately arranged. The plurality of light-emitting elements are respectively arranged in the first grooves. The plurality of wavelength conversion patterns are arranged in at least part of the plurality of first grooves and cover at least part of the plurality of light-emitting elements. The filter layer covers the isolation structure layer and fills the second grooves.

Description

technical field [0001] The present invention relates to a display technology, and in particular to a display panel. Background technique [0002] In recent years, under the condition that the manufacturing cost of Organic light-emitting diode (OLED) display panels is relatively high and its service life cannot compete with the current mainstream displays, Micro LED Displays have gradually attracted The investment vision of major technology companies. In particular, besides the optical performance comparable to OLED displays, such as high color saturation, fast response speed and high contrast, micro-LED displays also have the advantages of low power consumption and long service life of materials. Therefore, it is expected to become the mainstream display technology of the next generation. [0003] Considering the yield rate of die transfer and the difficulty of miniaturization of red light emitting diodes, a micro light emitting diode display using blue light emitting diod...
