Problems solved by technology

[0004] Mini-LED is used as an active light-emitting backlight source to replace the traditional reflective backlight, which can make the screen have higher contrast and clarity. However, the reflectivity of Mini-LED light panels on the existing market is generally 60%-70%. The highest can only reach 80% reflectivity

Embodiment 1

[0029] Such as figure 1 As shown, a preparation process for improving the reflectivity of Mini-LED lamp panels includes the following steps:

[0030] S1. Carry out the surface treatment process on the substrate of the Mini-LED light board, and then carry out oiling and first static treatment;

[0031] The surface treatment process in the above step S1 is a process of cleaning and deoxidizing the copper foil surface of the substrate by using a brushing operation; the purpose of the surface treatment is to clean and deoxidize the copper foil surface of the substrate before printing ink, thereby Increase the roughness of the copper foil surface to achieve higher ink adhesion; the specific implementation method of oil opening is: mix the main agent and curing agent in a ratio of 3:1, stir or shake for 10 minutes, or according to the mixing requirements Add a certain amount of diluent to dilute, diluent such as water, etc. can be.

[0032] The above-mentioned main agent is photos...

Abstract

The preparation process for improving the reflectivity of the Mini-LED lamp panel comprises the following steps: carrying out a surface treatment process on a substrate of the Mini-LED lamp panel, and then carrying out oil boiling and first standing treatment; s2, printing the substrate formed in the step S1, and continuing to perform second standing treatment after the printing treatment is finished; s2, performing pre-baking treatment on the substrate formed in the step S2, sequentially performing cooling and exposure after the pre-baking is finished, and continuing third standing treatment after the exposure is finished; performing development operation on the substrate formed in the step S3; performing thermocuring treatment on the substrate formed in the step S4; carrying out character silk-screen operation on the substrate formed in the step S5; according to the technology, the lateral erosion rate is smaller than 40%, the reflectivity reaches 88% or above, the manufactured backlight face can evenly reflect the luminosity of a backlight source, the reflectivity of light emitted by the reflecting lamp beads is higher, and the brightness value and the contrast value of the whole screen can be higher.

Description

technical field [0001] The invention relates to the technical field of Mini-LED manufacturing, in particular to a preparation process for improving the reflectivity of a Mini-LED lamp panel. Background technique [0002] Mini-LED is a backlight technology for LCD screens. In the past, the backlight of the screen was a whole piece. If it is on, it will be fully on, and if it is off, it will be fully off. Mini-LED uses a lot of lamp beads to light up the display, which needs to be displayed. Turn on some lights, and turn off the lights when you don't need them. It can be understood that the individual volume is reduced, the overall quantity is greatly increased, and the backlight LED light technology that can independently control the switch. [0003] In the past, the backlight of home TVs used direct-type and side-type light strips as the light source, coupled with the packaging method of the light guide plate, and used the reflection of light to generate the entire backlight...
