RINA TECH 32 inch backlight module product features
High brightness: It can provide sufficient brightness so that the TV screen can clearly display images under various ambient light conditions, and the screen content can be clearly seen even in a strong light environment.
Good uniformity: The LED lamp beads are evenly distributed, and with optical diaphragms and other components, it can achieve better backlight uniformity, reduce the phenomenon of uneven brightness on the screen, and enhance the viewing experience.
High color reproduction: The color and brightness of the backlight can be accurately controlled, which helps the LCD panel to better restore the true color of the image, present richer and brighter color effects, and make the picture more vivid and realistic.
Fast response speed: The LED lamp beads have a fast response speed and can quickly switch between on and off states. When displaying dynamic images, it can effectively reduce the phenomenon of smearing and make the picture smoother.
Energy saving: Compared with other types of backlight modules, direct-type LED backlight modules have a higher energy efficiency ratio, which can reduce energy consumption and save electricity costs while ensuring brightness and display effects.
Long life: LED lamp beads have a long service life, generally up to tens of thousands of hours or even longer, reducing the frequency of repair or replacement due to damage to the backlight module and reducing the cost of use.

Spare parts including

Product structure
LED lamp beads: They are the core light-emitting components of the backlight module. Their quality and performance directly affect the brightness, color and life of the backlight module. High-quality LED lamp beads have the characteristics of high luminous efficiency, low attenuation and good consistency.
PCB board: It is used to fix and connect LED lamp beads, and provide power and control signals for LED lamp beads. The design and quality of the PCB board will affect the heat dissipation performance and stability of the backlight module.
Optical film: It includes diffusion film, brightening film, reflective film, etc. The diffusion film is used to evenly diffuse the light emitted by the LED lamp beads to make the backlight more uniform; the brightening film can improve the utilization rate of light and enhance the brightness of the screen; the reflective film reflects the light emitted downward back to the direction of the LCD panel to reduce light loss.
Light guide plate: The light guide plate is also used in some direct-type backlight modules. It can guide and diffuse the light emitted by the LED lamp beads so that the light is more evenly distributed under the LCD panel. The design and manufacturing process of the light guide plate have an important influence on the uniformity and brightness of the backlight.
Frame and shell: used to fix and protect the various components of the backlight unit, and also play a role in heat dissipation and dust prevention. The material and structural design of the frame and shell will affect the overall stability and heat dissipation performance of the backlight unit.

RINA TECHNOLOGY backlight module

focuses on leading future lighting solutions

As a high-tech enterprise, RINA TECHNOLOGY has been focusing on the research and development, production and sales of optical LED products since it was established in Hong Kong in 2011, and provides one-stop optical lighting solutions. After years of rapid development, we have settled our R&D center and production base in Shenzhen, bringing together many senior technical experts and excellent management teams, especially in the field of backlight modules. We have accumulated rich experience and core technology.

We have advanced production equipment, including laser cutting machines, printing machines, film cutting machines, injection molding equipment, high-standard assembly workshops, BM-7 dust-free purification workshops and other automated manufacturing equipment to ensure that each backlight module meets high quality standards. Our daily production capacity exceeds 80,000 backlight modules, which not only meets the needs of the domestic market, but also actively expands overseas markets.

In the research and development of backlight modules, RINA TECH continues to break through innovation and overcome a number of core technical problems to ensure that the products have superior performance such as high brightness, good uniformity, low energy consumption and long life. We use self-developed high-precision optical materials and advanced assembly processes to improve the performance of backlight modules in LCD, car display, tablet computers and smart wearable devices.

After years of hard work, we have obtained a number of qualifications such as China Customs Registration Certificate and National Credit Cultivation Certificate, and have our own brand. In the international market, we have won a good reputation and established strategic partnerships with world-renowned companies such as LG, Samsung, and Lenovo.

The company adheres to the business philosophy of "establishing a business with integrity, market-oriented, and focusing on innovation", and upholds the corporate purpose of "excellence in production and benefiting society". We look forward to working with you to jointly promote the development of backlight technology and bring a clearer and brighter future to the world!

FAQ

1. Can a 32-inch direct-type backlight module replace an edge-entry backlight module? ​
Direct replacement is generally not recommended. The structural design, lamp bead position, and optical principle of the two modules are quite different. Replacement requires matching the panel size, drive circuit, shell structure, etc. of the TV. Forced replacement may cause display abnormalities (such as uneven brightness, color deviation), or even damage other parts of the TV. It is recommended to choose a backlight module type that matches the original model when repairing. ​

2. Will the brightness of the direct-type backlight module decay after long-term use? ​
There will be slight decay, but the decay rate is slow. The service life of high-quality LED lamp beads can usually reach more than 50,000 hours, and the brightness decay is not obvious within 3-5 years of normal use (the decay rate is generally less than 20%). If there is a sudden drop in brightness or a local dark area, it may be due to damage to the lamp bead, failure of the drive circuit, or aging of the optical film, which requires inspection and repair. ​

3. Is the power consumption of a 32-inch direct-type backlight module much higher than that of an edge-entry type? ​
Not necessarily. The number of 32-inch direct-type lamp beads is relatively large (usually 30-60), and the basic power consumption is slightly higher than that of the side-entry type (10-20 lamp beads), but the difference is not big (generally 5-10W). In addition, some direct-type modules support dynamic dimming, which can reduce the brightness of some lamp beads when displaying dark scenes. The actual power consumption may be close to that of the side-entry type, or even lower. ​

4. There are local dark spots in the direct-type backlight module. Is the lamp bead broken? ​
It may be a lamp bead failure or other reasons. If the position of the dark spot is fixed and the range is consistent with the coverage area of ​​a single lamp bead, it is likely that the corresponding lamp bead is damaged; if the dark spot is flaky or the edge is blurred, it may be that the optical film (such as the diffusion film) is damaged, the light guide plate is partially contaminated, or the reflective film falls off, resulting in abnormal light reflection. The module needs to be disassembled and checked one by one. ​

5. When assembling a TV, what installation details should be paid attention to for the direct-type backlight module?​
Ensure that the lamp beads are firmly connected to the PCB board to avoid cold soldering (otherwise it may cause flickering or partial non-lighting);​
The optical films need to be placed in order (usually from bottom to top: reflective film, light guide plate, diffusion film, and brightness enhancement film), and the edges of the films should be aligned to avoid wrinkles or offsets (affecting brightness uniformity);​
When installing the frame, apply uniform force to prevent squeezing of the film or lamp beads, and reserve heat dissipation space to avoid long-term high-temperature operation of the module affecting its life.
