In addition to microLED and OLED automotive display, Tianma also had a number of LCD-based displays for automotive.
MiniLED Backlight with Chip-on-Glass
One of the highlights was a 12.3-inch chip-on-glass demo. On one side, you see the full display; on the other, the LCD is removed to reveal the miniLED backlight. These blue LEDs, combined with a quantum dot (QD) film, deliver vibrant color and impressive brightness. The backlight uses 2,400 local dimming zones, enabling deep blacks and high contrast—key for automotive environments.
Local Dimming Trade-Offs on Larger Screens
Tianma also presented a 15.6-inch model to demonstrate local dimming effects. With dimming off, the background appears gray; with it on, blacks are much deeper. However, enabling local dimming reduces peak luminance—a challenge Tianma is actively addressing through improved algorithms for zone management.
InvisiVue: Textured Displays for a Premium Feel
Another eye-catching innovation was InvisiVue textured overlays. These are applied to miniLED panels to create unique tactile experiences. One example featured the same 12.3-inch display in portrait mode with a highly textured surface offering about 50% transmissivity, ensuring brightness remains strong. Other versions include smoother finishes, some with integrated touch functionality.
Smart Sensing for Driver Comfort
Tianma demonstrated a driver-monitoring system using near and far infrared sensors. The near IR sensor, equipped with a germanium window, measures skin temperature to automate climate control adjustments. Imagine your car turning up the AC when you’re feeling warm—no manual input required.
Haptic Feedback for Enhanced Interaction
A haptic feedback demo showcased piezoelectric actuators beneath the surface. The strongest setting delivered a satisfying click, while weaker responses felt less noticeable. This technology could redefine how drivers interact with touchscreens, adding a physical dimension to digital controls.
Privacy Screens with Branding Potential
Finally, Tianma introduced a privacy screen concept developed with Rain Technology. In normal mode, the screen looks standard, but it can switch to dark or display branding—such as the Rain or Tianma logos. This opens up intriguing possibilities for advertising and personalization inside vehicles.
Why It Matters
Automotive displays are evolving beyond simple screens. Tianma’s demos show a future where visual quality, tactile feedback, smart sensing, and branding converge to create a richer, safer, and more personalized driving experience.
