DMD Chip Selection Guide: Texas Instruments DLP for Projectors

Texas Instruments (TI) is the sole supplier of DMD (Digital Micromirror Device) chips for DLP projectors, making DMD selection a critical decision for any projector OEM buyer. DMD chip selection affects image quality, BOM cost, lead time, and product roadmap. This guide explains the available DMD options, the trade-offs, and how to choose the right chip for your projector SKU.

How DMD Chips Work

A DMD chip contains millions to billions of microscopic mirrors on a silicon die. Each mirror represents one pixel and tilts thousands of times per second to direct light either toward or away from the projection lens.

Key specs:

• Resolution: number of mirrors (pixels)
• Pixel pitch: distance between mirror centers
• Mirror tilt angle: typically ±12° or ±17°
• Switching speed: microsecond response time

Higher resolution = smaller mirrors = smaller pixel pitch = more challenging optical design.

The Current DMD Lineup

On the high-brightness side, the GP98 12400 Lumens Smart Projector for Meeting Rooms is our flagship reference platform for ODM partners—laser-phosphor light source with a sealed optical block.

Distributors evaluating the B2B projector market can reference our GP94C Android Smart Projector for Home Theater—a production-validated platform covering Android 9 · 500 ANSI · Built-in Speakers, suitable as an OEM/ODM starting point.

Choosing the Right DMD

Decision factors:

1. Target Resolution

Target Resolution	DMD Options
720p	0.23" XPR to 720p
1080p	0.33" native, 0.47" native
4K	0.47" XPR, 0.66" XPR, 1.38" native
WUXGA	0.66" native

2. Target Brightness

Higher brightness can drive larger DMD selection:

• < 500 ANSI: 0.23" or 0.33" DMD
• 500–1,500 ANSI: 0.33" or 0.47" DMD
• 1,500–4,000 ANSI: 0.47" or 0.66" DMD
• 4,000+ ANSI: 0.66" or 1.38" DMD

3. Form Factor Constraints

Smaller DMD = smaller optical engine = smaller projector:

• Pocket size: 0.23" DMD
• Portable: 0.33" DMD
• Mainstream consumer: 0.47" DMD
• Commercial / premium: 0.66" or 1.38" DMD

4. BOM Cost Targets

DMD cost ranges (1,000-unit volume):

DMD	Cost Range
0.23" 1080p XPR	$5–$15
0.33" 1080p	$12–$25
0.47" 1080p	$15–$30
0.47" 4K XPR	$25–$60
0.66" WUXGA	$40–$80
0.66" 4K XPR	$60–$100
1.38" 4K	$150–$300

5. Lead Time Considerations

TI DMD lead times:

• Mainstream (0.33", 0.47"): 4–14 weeks
• Newer (0.16", 0.23"): may be longer due to allocation
• Premium (1.38"): 12–20 weeks

For OEM buyers, mainstream DMDs are easiest to source. Premium DMDs (1.38" 4K) require longer planning.

DMD Allocation Challenges

Texas Instruments allocates popular DMDs to its largest customers. Common scenarios:

• Allocation: DMD supply limited; customers placed on allocation
• Lead time extension: standard lead time 4 weeks becomes 14+ weeks
• Last time buy: DMD discontinued, final purchase opportunity

For OEM buyers, dependency on a single DMD supplier is a strategic risk. Strategies:

• Use multiple DMD options per SKU (designed to accept either 0.33" or 0.47")
• Maintain 6-month safety stock for mature SKUs
• Track TI DMD roadmap for new chip releases

The XPR Pixel-Shifting Trade-off

XPR (eXpanded Pixel Resolution) is TI's pixel-shifting technology. A 1080p DMD shifts at 240Hz to display 4 distinct positions per pixel, creating 8.3 million distinct pixel positions on screen — equivalent to 4K resolution.

Trade-offs:

Aspect	Native 4K	XPR 4K
True resolution	4K	Effectively 4K
Pixel visibility at close range	Negligible	Minor
DMD cost	$150–$300	$25–$60
Optical engine complexity	Higher	Lower
Consumer perception	"Real 4K"	"Pixel-shifted 4K"

For most consumer applications, XPR 4K delivers excellent perceived image quality at much lower BOM cost. For premium home theater buyers, native 4K is preferred.

DMD Chip Roadmaps

TI regularly introduces new DMDs:

• 2024+: 0.16" DMD for ultra-compact
• Ongoing: Higher-resolution variants of existing sizes
• Premium: Improved 1.38" variants for home theater

For OEM buyers, tracking TI's roadmap is important:

• New chip introduction = cost reduction opportunity
• Chip EOL = migration planning required
• TI design support = free for qualified customers

Most major OEM factories have direct relationships with TI for DMD allocation and roadmap visibility.

The DMD Replacement Market

For long-term OEM buyers, DMD replacement (warranty / repair) matters:

• TI continues to supply mature DMDs for 5–10+ years after introduction
• Allocation may apply to replacement volumes
• For mature SKUs, plan for replacement DMD supply

For OEM buyers, this means:

• Choose DMDs with proven longevity
• Maintain tooling for DMD replacement
• Stock spare DMDs for warranty service

OEM Specification Best Practices

When specifying DMD in your RFQ:

DMD CHIP SPECIFICATION

Manufacturer: Texas Instruments (TI) DMD model: [e.g., DLP470NE for 0.47" 1080p] Native resolution: 1920×1080 (or specify XPR if pixel-shifted) Pixel pitch: [µm] Mirror tilt angle: ±17° (typical) Operating temperature: 0–70°C (typical) Package type: [specific TI package] Required support: TI DMD datasheet Reference design availability TI technical support contact Allocation / lead time confirmation EOL policy (typically 5–10 years notice)

DMD Lifetime and Reliability

DMD reliability specs:

• Operating life: > 100,000 hours (limited by light source, not DMD)
• Operating temperature: 0–70°C (chip), 0–45°C (projector ambient)
• Storage temperature: -40 to +80°C
• Mechanical shock: 1,500 G (DMD chip itself is rugged)

Field failures are rare. Most DMD-related failures are actually:

• Thermal damage (overheating)
• ESD damage (improper handling during manufacturing)
• Optical contamination (dust between DMD and prism)

Mitigation: clean room assembly, ESD protection, proper thermal design.

Common OEM Mistakes

Five pitfalls:

1. Specifying DMD without confirming allocation — popular DMDs on allocation
2. Single-source DMD — risk if DMD goes on allocation
3. Ignoring DMD EOL policy — DMD discontinued mid-product life
4. Skipping ESD protection in production — DMD damage during assembly
5. Insufficient thermal management — DMD overheating, mirror failure

DMD vs LCD vs LCoS

Quick comparison:

Attribute	DLP (DMD)	LCD (3LCD)	LCoS (SXRD/D-ILA)
Native contrast	1,500:1 to 5,000:1	1,000:1 to 3,000:1	5,000:1 to 30,000:1
Response time	Microseconds	Milliseconds	Milliseconds
Color brightness	~80% (color wheel)	100%	95–100%
Pixel visibility	Some	Visible	Minimal
BOM cost	Moderate	Low	High
Supplier	TI (sole)	Epson, Sony	Sony, JVC

For most consumer OEM, DLP (DMD) is the standard choice.

What We Recommend for DMD Selection

1. 0.47" DMD for mainstream consumer (best balance)
2. 0.33" DMD for portable / mini projectors
3. 0.66" DMD for commercial / WUXGA applications
4. 1.38" DMD for premium home theater only
5. Track TI roadmap for new chip introductions
6. Confirm allocation before committing to specific DMD

Conclusion

DMD chip selection is a strategic decision that affects cost, image quality, and supply chain. Work with a factory that has strong TI relationships, track TI roadmaps actively, and plan for allocation risk.
