Problems solved by technology

In terms of LCD screens that are sold in large quantities and are not expensive, it is indeed possible to directly replace one; however, since QD-LCD is in the research and development stage and has not yet entered mass production, its price is not cheap , so that when a QD-LCD screen is formed and the screen fails, it does not seem to be cost-effective to directly replace a new QD-LCD screen

Embodiment Construction

[0041] The present invention mainly relates to a micro-light-emitting diode quantum-dot display screen, in particular, a repair structure for a micro-light-emitting diode quantum-dot display screen with vacant quantum dots. As mentioned above, the current quantum dot display technology is gradually maturing. Since it is superior to the current liquid crystal display in terms of luminous height and resolution, the era of it as a replacement for the current liquid crystal display is just around the corner. Since the micro-light-emitting diode quantum dot display has the characteristics of a plurality of quantum dots, and each quantum dot also has fluorescent powder independent of other quantum dots, it provides the user with a fluorescent powder in at least one When the filled quantum dots fail, there is a chance to repair the faulty display screen.

[0042] The main purpose of the present invention is to provide a repair structure of a micro-light-emitting diode quantum dot dis...

Abstract

The invention discloses a micro light emitting diode quantum dot display repair structure. The structure is mainly characterized by comprising steps that a distributed Bragg reflector (DBR) is removed; vacant quantum dots are filled with the fluorescent powder; a Bragg mirror is placed to cover the micro light emitting diode quantum dots arranged in a matrix mode entirely.

Description

technical field [0001] The present invention mainly aims at providing a repairing structure of a display screen, especially a repairing structure of a display screen formed by quantum dots of micro-light-emitting diodes. The specific field is when there is a certain or Repair structure when certain micro-quantum dots fail to emit preset colors. Background technique [0002] The composition of sapphire is alumina (A1 2 o 3 ) is covalently bonded by three oxygen atoms and two aluminum atoms. The crystal structure is a hexagonal lattice structure. The optical transmission band of sapphire is very wide, from near ultraviolet (190 nanometers; nm) to mid-infrared All have good light transmission, and have the characteristics of high sound velocity, high temperature resistance, corrosion resistance, high hardness, high melting point (20452°C), so they are often used as substrate materials for optoelectronic components. [0003] The quality of ultra-high-brightness white / blue LED...
