Abstract

The invention discloses a quantum dot color film substrate and a preparation method thereof, a display panel and a display device. The quantum dot color film substrate comprises a base, a retaining wall layer and a reflecting metal layer. The retaining wall layer is positioned on one side of the substrate, and comprises a plurality of retaining wall structures and a plurality of retaining wall openings. The reflecting metal layer covers the side surface of the retaining wall structure, and is used for reflecting light emitted by a light-emitting unit to improve the utilization rate of emergentlight. Meanwhile, the reflecting metal layer is also used for receiving a touch signal for touch detection. According to the quantum dot color film substrate, the touch function is integrated in thequantum dot color film substrate, the touch function is achieved without an externally-hung touch panel, the number of film layers of the quantum dot display panel can be reduced, and therefore the overall thickness of the quantum dot display panel is reduced, and the requirement of users for a light and thin quantum dot display panel is met.

Description

technical field [0001] The present application relates to the field of display technology, and more specifically, to a quantum dot color film substrate and a preparation method thereof, a display panel and a display device. Background technique [0002] Quantum Dot (Quantum Dot) display is a new type of display technology, which has the characteristics of improving the color gamut and contrast of the display device. [0003] refer to figure 1 , figure 1 It is a schematic cross-sectional structure diagram of a quantum dot display device, limited by the special structure of the quantum dot display device, most of the ways to integrate touch functions in the quantum dot display device are plug-in, that is, through an optical display panel 1 on the quantum dot display The adhesive 2 is used to bond the integrated touch panel 3 . The side of the touch panel 3 facing away from the quantum dot display panel 1 needs to be bonded with the cover plate 5 through another layer of opti...
