TI DLP® Pico™ Technology for Appliance Displays
1 Application Brief
Appliance displays have traditionally been limited to monochrome alphanumeric displays, like those on microwaves and ovens. Some newer appliances integrate displays with higher resolutions and full color. Appliance manufacturers seeking to differentiate their products should consider projection displays that can create an image on virtually any surface.
Features and Benefits
| On-demand displays on a variety of surfaces | Project on countertops, stovetops, cutting boards, transparent glass, floors, and more - displays in helpful places when you want them, and invisible when off |
| High optical efficiency/low power | Brighter displays given power and size constraints |
| High contrast | On/off contrast ratio of >1000:1 are possible, dependent on optical design tradeoffs, which enables more vivid images and lower black levels |
| Compact projection systems | Digital micromirror device (DMD) arrays as small as 0.16” diagonal enable extremely compact projection systems that can fit in just about any product |
Recommended Chipsets for Appliances
The DLP® Pico chipset portfolio offers several solutions. The best fit will depend on target size, power, & performance level of the display system.
For smaller, lower brightness systems, DLP Pico chipsets that include a 0.16” or 0.2”-class micromirror array diagonal are recommended. These solutions enable extremely compact optical systems and the lowest possible power consumption.
For higher performance display systems, the 0.3” and 0.4”-class of DMDs enable higher brightness levels.
| Smallest Size, Lowest Power | Small Size, High Resolution | High Brightness, High Resolution |
|---|---|---|
| DLP160AP (180p) DLP160CP (360p) DLP2010 (480p) DLP230GP (540p) | DLP230KP (720p) DLP230NP (1080p) | DLP3010 (720p) DLP3310 (1080p) DLP4710 (1080p) |
Brightness and DMD sizes for image sizes
| Image Diagonal (inches) | Brightness Output (Lumens) (1) | DMD Diagonal (inches) |
|---|---|---|
| 5" | 10 | ≥0.16” |
| 10" | 45 | |
| 15" | 100 | ≥0.2” |
| 20" | 175 | |
| 25" | 300 | ≥0.23” |
| 30" | 400 | ≥0.3” |
