CES is the world's largest consumer electronics show, which will be held in Las Vegas from January 5th to January 9th, 2023. We sort out the consumer electronics products that have received much attention for readers' reference.
Automotive Lighting and Display
Showcasing a series of driver IC products used in automotive lighting and automotive display.
1.Adaptive High Beam
At present, high-end car manufacturers have launched car models with adaptive headlights. The operation method is to arrange multiple LED lights into a matrix-shaped headlight. Each LED light has an independent lighting function. It is equipped with a lens module to comprehensively consider environmental information. After changing the location, location and even the driving speed, the irradiation angles of the high beam and low beam will be changed accordingly to improve the safety of driving and surrounding vehicles; the more LEDs, the more flexible the irradiation area can be adjusted.
The advantages of adaptive headlights are: it does not affect driving visibility, avoids strong light interference to oncoming vehicles, and can also illuminate objects and road signs.
2.through tail lights
In recent years, automakers have successively introduced LED lights into the application of taillights. What they are looking for is the sense of technology and exquisite design that LED lights bring to the car models. The car factory designs the taillights or the third brake light in the center into a strip shape or a narrow and long shape, forming a through-type taillight, which achieves visual extension by increasing the light-emitting area, and is more recognizable after being lit at night; the higher-level design is Equipped with independent light point control function, the tail light module can program dynamic welcome light effects in a more varied way.
The exhibits use the accumulation driver chip MBI5353Q that meets the automotive safety integrity level ASIL A. The module LED light spacing is 0.9375mm, which can independently control the characteristics of the LED light points. It is used for through-type taillights, making the lighting effects more varied and helping the appearance of the car model The design is more and more colorful.
3.HDR car display
MBI5353Q provides 16-bit grayscale, and only one driver chip can control the dimming area up to 1,536 areas, which can not only bring fine images to small-sized displays, but also make the display brighter under sunlight due to the high brightness of the LED. View the display without interruption.
MBI6353Q, its Hybrid dimming technology can generate excellent low-gray color rendering effect, and the environmental information can still be clearly captured even in dim light; in addition, Macroblock’s LED backlight driver chip can provide automakers with extended application functions Or a flexible functional design option that simplifies circuit design.
Micro LED Smart AR Glasses
In 2022, we will pay attention to the Metaverse issue of the big explosion, which has naturally become one of the six themes of this CES exhibition, including Nvidia’s release of Digital Tiwns computing solutions, and Qualcomm’s release of a brand new smart glasses platform Snapdragon AR2 Gen1 (officially announced its performance It is 2.5 times that of the current XR2 platform), and the active efforts of many major manufacturers have continued to increase the attention of Metaverse.
As smart AR glasses are an important vehicle for the development of the Metaverse concept, several products equipped with Micro LEDs as light engines were also unveiled at this exhibition.
Vuzix, a major AR/VR and wearable display manufacturer, showcased the new smart glasses Ultralite. This product combines Micro LED and optical wave guide technology. Under the extension of the fashion, light and integrated design concept, its weight is only 38 grams, and it can be used directly The size that can be stored in a general glasses case is also a highlight that is different from other products of the same type.
Mini LED Backlight TV and Monitor
How does the display create the next generation of new display in a seamless way based on the existing LCD and backlight display technology, and compared with the traditional backlight display, it can present the effect of high contrast and high image quality, adopting the technical threshold Low-profile Mini LED backlit displays will become an important option for display brand manufacturers to deploy new products in the future. Therefore, manufacturers such as Samsung, Hisense, TCL, Skyworth, Sharp, and others will launch Mini LED backlit TVs before and during the 2023 CES show.
Among IT displays, NB adopts Mini LED backlight display size, which has already got rid of the middle and high-end market of 16” and above in the past, and will extend downward to the traditional backlight display market dominated by 14”, which will have the opportunity to increase the penetration of Mini LED backlight in NB.
In addition, in the application of MNT, the Mini LED backlight focuses on the e-sports market, and the display covers the player's field of vision to increase the sense of presence in the game, making the size of the display gradually enlarged.
Mini LED backlight products are still closely related to high-resolution (2K and above) and e-sports (240Hz and above) specifications. Obviously, for the layout of the mid-level or entry-level Mini LED backlight market, brands still cannot find a suitable entry for the time being. Point, this is closely related to the high cost of Mini LED backlight.
Therefore, in Mini LED backlight displays, how to effectively reduce the usage of Mini LED and quickly reduce the cost has become the most important issue at this stage. At present, TENGIFTS, through the unique LED optical lens design, can effectively control the Mini LED light-emitting angle and optical uniformity. Therefore, compared with the traditional Mini LED optical solution, the usage of Mini LED can be reduced by about 60~ 75% of the dosage can still maintain good optical uniformity, which will provide a unique solution for improving the competitiveness of Mini LED backlight products.
