OLEDIt was once considered the absolute winner of the next generation of high-end displays. However,LCDContinuously improving and narrowing the performance gap, new technologies continue to emerge. among which,MiniLED、MicroLEDAs a competitive advantage in high-end display applications, it has attracted widespread attention.

Let's talk firstMicro LEDTechnologyThat isLEDMiniaturization and matrix technology, in simple terms, refers to the process ofLEDBy thinning, miniaturizing, and arranging the backlight source of light-emitting diodes, it is possible to achieveLEDUnit less than50Microns, individually driven luminescence (self luminescence). Its advantage lies in inheriting both inorganic and inorganic materialsLEDIt has the characteristics of high efficiency, high brightness, high reliability, and fast response time, as well as the self luminous feature without the need for a backlight source. It is small in size, lightweight, and can easily achieve energy-saving effects.

From the perspective of structural principles,Micro LEDSimpler and more effective,TFTSubstrate, ultrafineLEDGrains, driversICIt's not a big problem, but its biggest challenge is the well-known massive transfer, how toLEDTo achieve miniaturization, it requires a wafer level process level.

Mini LEDCompared to the manufacturing processMicro LEDHigh yield, with irregular cutting characteristics, can also achieve a high curved backlight form when paired with a soft substrate. It adopts a local dimming design, which has better color rendering and can bring more refined LCD panelsHDRPartition, and the thickness is also approachingOLED, can save electricity up to80%Therefore, in order to save electricity, reduce thicknessHDRThe demand is for backlight applications such as irregular displays, which are suitable for use in products such as mobile phones, televisions, car panels, and gaming laptops.andMicro LEDcomparison,Mini LEDThe yield is higher, the technical difficulty is lower, the cost is lower, and it has obvious advantages in mass production.We can develop a large market for LCD backlight sources, resulting in better product economy.

Mini LEDTechnology can be directly applied toRGBDisplay, can also be used forLCDThe backlight module. among themLCDIn the screen backlight module, it is mainly achieved through the use ofMini LEDTechnological improvements in display performance.

itsMini LEDThe technical principle is：Mini LEDAdopting a direct backlight method, it can be considered as a regular backlightLCDUpgraded version of the screen.Mini LEDCarry forward traditionLEDReduce the size of backlight beads to achieve more precise and dense backlight partitioning, in conjunction withLocal DimmingControl, improve brightness and contrast, enhance visual perception. Under the same conditions of comparison,Mini LEDNot only did it make up for itOLEDThe disadvantage of being prone to screen burn-in and being more cost-effective than othersOLEDAt the same time as improving the visual quality, it also has a cost advantage.

According to recent media reports, the industry believes that in carMini LEDwill be from2023Starting from the beginning of the year, the volume is expected to increase2025Annual market size reaches450Ten thousand pieces, with a compound annual growth rate of up to159%The automotive market will becomeMini LEDNew growth points.

 According to a research report by Zhongtai Securities, in terms of application, the overallballMini LEDDisplay device inVRThere has been significant growth in fields such as automotive, display, etc.MiniLEDBacklight display technology,significantly improvedLCDThe performance of, while utilizing existingLCDManufacturing production lines and requiring almost no additional capital expenditures.

asLCDThe "behind the scenes hero" backlight source displayed is constantly updated and upgraded in the continuous development of technology and market. From the very beginningCCFLBacklight toSMD LEDBacklight, quantum dot backlight, and nowMini LEDBacklight, with the continuous development of backlight technologyget, obtain, gainLCDThe display effect has been continuously improved, allowing people to enjoy the feast of ultra high definition vision.

Compared to traditional methodsLEDBacklight source,Mini LEDThe backlight performance has the following improvements, suitable for high-end LCD display solutions:

·The backlight chip has a small structure, which is conducive to dividing the number of dimming zones（Local DimmingZones）More meticulous workmanship, resulting in a higher dynamic range（HDR）To achieve a higher contrast effect.

·Mini LEDCan achieve high brightness (>1000nit）Uniform heat dissipation belowThis is a traditional separationLEDThe device solution cannot achieve it.

·Mini LEDBacklight can achieve a direct and ultra-thin designLCDdisplayShorten the optical mixing distance（OD）That isOD≈0mmReduce the overall thickness to achieve ultra-thin design. This has broad applications in lightweight portable consumer electronics, such asAR/VRGlasses, mobile phones, laptops, etc.

·Mini LEDCombining fine detailsLocal Dimming，Can achieve ultra-high contrast(1000000:1)Make the black deeper and the light brighter. In terms of core parameters such as brightness, area control, lifespan, and color performance, it can surpassOLED.
