Description

Technical Field

[0001] The invention relates to the technical field of quantum dot substrates, in particular to a quantum dot substrate. Background Art

[0002] A quantum dot is a semiconductor nanostructure that binds excitons in three spatial directions. Sometimes called "artificial atoms" or "quantum dot atoms", it is a new concept proposed in the 1990s. This constraint can be attributed to electrostatic potential (generated by external electrodes, doping, strain, impurities), the interface of two different semiconductor materials (for example: in self-assembled quantum dots), the surface of a semiconductor (for example: semiconductor nanocrystals), or a combination of the above three. Quantum dots have separate quantized energy spectra. The corresponding wave functions are spatially located in the quantum dot, but extend over several lattice periods. A quantum dot has a small number (1-100) of integer electrons, holes, or hole-electron pairs, that is, the charge it carries is an integer multiple of the elementary charge.

[0003] When the existing quantum dot substrate is in use, a large number of quantum dots are used to ensure the improvement of the brightness of the display screen, so the quantum dots consume a lot of power, have low light utilization and short service life. Water vapor and oxygen in the air will affect the light color conversion rate of the quantum dots. At the same time, when the quantum dot film is in use, the two types of quantum dots will affect each other, resulting in performance degradation and poor reliability of the film. When the quantum dot substrate is in use, the internal power consumption is large and the heat generated is large. If it is in a high temperature environment for a long time, the luminous efficiency of the quantum dot film will be low, and even damage to the quantum dot substrate will be caused, affecting the service life of the quantum dots, and also bringing certain economic losses.

When the quantum dot film 24 is used, the two quantum dots will affect each other, resulting in performance degradation. The reliability of the quantum dot film 24 is poor, and the light source is focused by the convex film 32, and the light The light source passes through the light-transmitting plate 34 and is refracted and reflected by the reflective baffle 33 to achieve a greater lighting effect.

As the wire rope 45 slides downward, it drives the second steel wire rope 51 downward, and the second steel wire rope 51 drives the second steel wire rope net 52 downward. The second steel wire net 52 slides downward and squeezes the sponge 37. Since the second connecting groove 36 is vertically arranged downward, the second steel wire net 52 squeezes downward to squeeze out the remaining water vapor in the sponge 37.
