As LCD technology is relatively mature, a comprehensive standardized system has been established for the sector with high quality products, sufficient production capacity and a strong cost advantage. Thus, LCD is currently the major technology for VMDs.
However, when the aforementioned automotive trends emerge, LCD will fail to meet the requirements of high-end automotive LED car display systems due to inadequate brightness output, faster temperature rise and limited visual effects. Under such circumstances, LED—with increasingly clear technological advantages—are expected to dominate the VMD market for years to come.
LED, an organic self-luminous component, is known for excellent LED car display effects, low energy consumption, high flexibility and ultra-thinness, which has been applied to high-end vehicles.
OLED VMDs are mainly provided by Samsung, LGDisplay and BOE. However, problems of screen burn-in—a major issue for OLED displays despite years of development—as well as the short lifespan of most OLED blue lights have impeded further advances of the technology in the VMD sector.
LED technology can be combined with flexible substrates to realize curved display design with enhanced brightness and contrast, thereby adding flexibility to in-cabin screen design. Nevertheless, compared with its OLED counterparts, LED car displays tend to be thicker with limited bendability.
