The 2022 Guangzhou International Lighting Exhibition (GILE) will be held from June 9 to 12, 2022 at the China Import and Export Fair Complex. Guangzhou International Lighting Exhibition shares with you today's lighting industry information:
What are the advantages of Mini LEDs?
According to Guosen Securities Research Report, Mini LED currently has two development paths: backlight and direct display, of which backlight technology is already in a mature period of commercialization.
Compared with the traditional LED backlight, Mini LED backlight has advantages in brightness, contrast, color gamut and other display effects and thinness; compared with OLED, Mini LED backlight has cost advantages, and the display effect can be comparable to OLED.
Mini LED backlight in the retention of LCD advantages at the same time, but also integrated into some of the characteristics of OLED, with energy saving, thin and light, wide color gamut, high contrast, fine dynamic partitioning and other advantages, Guosen Securities said, in addition to the display, personal computer field, VR/ AR is also expected to become one of the key application areas of Mini LED backlight.
MiniLED backlight unlocks the metacosm display code
From TVs to computers, from mobile phones to wearables, from outdoor advertising to in-car central control, and VR devices in the meta-universe, MiniLED backlight technology continues to expand application scenarios. For example, the PimaxReality 12K QLED VR headset device is equipped with a MiniLED backlit display, which measures 5.5 inches and integrates 5000 MiniLED, which has the advantages of wide color gamut, high contrast, high HDR, faster response speed, etc., which helps users feel the realism in the metaverse.
MiniLED backlit - BT board
The Mini LED backlight display shows a high level of performance that makes it the choice of its time. The unit area is laid out with a large number of MiniLED, in order to obtain a realistic display effect at the same time corresponding to the power consumption, softness, size, thickness and thinness of the higher requirements, the key to all this is in the MiniLED backlight board, how to achieve smaller spacing and smaller MiniLED transfer fit, has become the key to all this.
Zhuoxing Semiconductor comprehensively solves the difficulty of inverted COB solid crystal
The sudden explosion of 2021, known as the metaverse metaverse, has reawakened the enthusiasm of VR/AR equipment manufacturers, responding to technological upgrades and adopting more advanced MiniLED backlight technology in display applications. The key to the realization of this technology is in the packaging process of the backlight board, and the flip COB is the best choice for the realization of MiniLED backlight light board technology.
To complete the packaging process of the MiniLED backlight plate, the flip COB has extremely high requirements for the solid crystal machine.
First, the fit should be more accurate, to meet the position error <± 15um, the angle error < 1 °;
Second, the substrate should be larger, with a width of more than 200mm;
Third, the lamination speed should be fast, and it must be denatured before the denaturation of the solder paste; the denaturation yield must meet the commercial standards of MiniLED, reaching more than 99.99%. The above strict requirements make ordinary solid crystal machines "prohibitive".
Zhuoxing Semiconductor backlight solid crystal machine 3602P
Zhuoxing Semiconductor launched the "3C Solid Crystal Law", which perfectly resolved the solid crystal "pain points" faced by the MiniLED backlight substrate with three major steps: Correction, Control and Continuity. Through the two-step process of wafer ring correction and wafer correction, the chip fit is more accurate and the spacing is smaller. Continuous solid crystals are completed in the mode of double-arm veneer, which is twice as efficient as ordinary single-arm veneer and double-plate solid crystals. Double-arm split-side solid crystal can also make the substrate size larger, and in the face of large size substrates there is a warpage "difficulty", Zhuoxing Semiconductor backlit solid crystal machine through pressure control to achieve a stable chip fit, to ensure the solid crystal yield. The yield of ZÖCH Semiconductor backlight solid crystal machine is as high as 99.999%, which is much higher than the commercial standard of MiniLED backlight.
Some industry experts predict that the output value of MiniLED backlight panels will increase from 608 million US dollars in 2021 to 6.168 billion US dollars in 2025, ten times the increase, and the future can be expected!
As a bellwether of the lighting and LED industry, the 2021 Guangzhou International Lighting Exhibition showcases cutting-edge optoelectronic innovation technologies and integrated solutions for design, home, architecture, hotels, supermarkets, project engineering, agricultural planting, medical treatment, education and other fields, with a total of 97,688 visitors, including more than 30 industry associations, government agencies and leading enterprises invited to attend. At the same time, more than 250 professional seminars, forums and immersive works exhibitions were held to help enterprises keep up with the policy trends of industry development.
The 27th Guangzhou International Lighting Exhibition (Guangya Exhibition) will be held from June 9 to 12, 2022 at the China Import and Export Fair Complex. GILE2022 will take "New Era, New Responsibility" as the theme, coupled with the main line of "thinking and doing something", and once again join the industry in this grand event! The three highlights of the exhibition launched the exchange of the two ecosystems of "intelligence" and "optical application"; gathered the cross-industry application display of "cultural tourism and optical art", "smart city" and "new energy"; and focused on the main axis of the "Power of Design and Technology" forum.
