El blog Alrededor Rogins FOG LCD Displays Advance Highdefinition Projection Tech

The quest for superior visual experiences has driven significant innovation in projection display technology. At the heart of this evolution lies the LCD (Liquid Crystal Display) screen, which serves as the critical optical modulator determining image quality in projection systems.

Market Demands and Technical Evolution

Modern projection technology requires efficient conversion of digital signals into visible light. FOG (Chip-on-Glass) LCD displays have emerged as the industry standard, integrating driver ICs directly onto glass substrates to reduce module size while enhancing reliability.

Key performance metrics driving development include:

• Resolution: Ranging from 720(RGB)×1280 to 1920(RGB)×1080, higher resolutions deliver sharper, more detailed images
• Size: Display diagonals from 2.0 to 6.7 inches accommodate diverse device designs
• Interface: Multiple options including MIPI, LVDS, RGB and SPI balance speed, power consumption and cost
• Transmittance: Higher light transmission enables brighter projection output
