Combining the development of the industry itself, the Forward-looking Industry Research Institute predicts the development trend of LED chips in the three major traditional applications of backlighting, lighting, and display in 2018 as follows:
1, LCD backlight
The LCD itself does not emit light. It is necessary to add a backlight to the bottom of the LCD panel to display the screen. When the color display was first commercialized, the backlight source was CCFL (Cold Cathode Fluorescent Cathode), which was subsequently replaced by LEDs. LED backlights for consumer electronics such as mobile phones led the first wave of high-brightness LED demand growth. Although OLED is replacing LCD, the large-size TV field will still be dominated by LCD. Under the trend of large size and high brightness, the demand for backlight LED will gradually increase.
2. Lighting
The application of LED in the lighting field can be divided into general lighting (indoor lighting, outdoor lighting), automotive lighting, landscape lighting, and other subdivided fields. Due to the advantages of simple structure, long service life, pure color, and low energy consumption, LED light sources can quickly replace traditional lighting methods. At present, lighting is the largest application area of LED. General lighting and landscape lighting continue to penetrate, and automotive lighting and other subdivided areas show a high growth status.
3, display
LED display has high brightness and large size, so it has unique advantages in the field of outdoor large screen display. In recent years, technological progress has led to a rapid decline in the cost of small-pitch (below 2.5mm pitch) LED display screens. Small-pitch LED displays have shown explosive growth in large-screen displays and commercial markets. Currently, LED is the second largest segment of LED. Application area.
On the whole, the downstream applications of LED chips continue to widen, making the future demand for corresponding LED chips continue to grow at a high speed.
