Truly s Technologies for Automotive LCD I ETN (Enhanced TN): Negative TN with Dye-doped LC to enhance higher contrast at specified backlight, such as amber/red/white BL. ESTN (Enhance STN): Negative STN with Dye-doped LC to enhance higher contrast at specified backlight, such as amber/red BL. Better performance at high temp than normal STN. DSTN (Double STN, with or without heater): Good contrast at low temp and high temp because of LC delta N compensation. ASTN (Advanced STN, using special polarizer): High Temp-compensation like DSTN, but thinner and lighter than DSTN.
Truly s Technologies for Automotive LCD II TBN (True Black Negative): Vertical alignment mode with true black background. Contrast can be easy higher than 1000. It s good for high contrast and wider viewing angle application inside the automotive. ADM-LCD (Auto-Dimming Mirror LCD): For safety at night Used for rearview mirror inside or outside the automotive. PDLC display (Polymer dispersed LC display): For safety at night Used for frontview mirror inside the automotive. ITO-HEATER: For improving response time at low temperature such as 40c. Custom design for various dimensions and heating ratios are possible.
Truly s Technologies for Automotive LCD III Free Shape LCD: Free shape LCD such as corner cutting, hole drilling, etc. to attain mechanical and dimensional matching. Black mask with color printing for car audio application. Screen printing color on glass or polarizer. ACN (Area Color Nematic): This technology can make passive LCD display color performance, and very similar to TFT display, but the development cost and unit price are lower very much comparing to TFT. Driving method is totally same as normal mono display, no need to use color driver IC, that s to say, if customer want to upgrade from mono to color, we only need change the display, and will not impact customer s software or hardware.
Truly s Technologies for Automotive LCD IV CSTN: Full color, available 65k colors. For automotive information display. Touch Panel: F-G type for aftermarket, G-G type for before market. OLED: Self-emissive display, no backlight needed. Thinner structure. Passive addressing now available, while active matrix addressing will be used for higher resolution. TFT: High resolution, high color performance, color and monochrome. for entertainment, information board or navigator.

Primary focus is Automotive, Industrial and Medical products. A new TFT fab. that can meet the needs of customers over the next 15~20 years with stable, high quality and reliability production.
Truly s Product for Automotive application IV TRULY Mono-TFT Strategy: Mono-TFT has the same performance (high contrast, wide viewing angle, fast response time) as full color TFT. Unit price: 1. unit price is much lower than color TFT. 2. unit price is a little higher than DSTN/ASTN, but display performance is better than DSTN/ASTN very much. So mono-tft is an ideal high performance display for automotive in further. Mono-TFT: Normal white and Normal black.
