5.1 Brightness

Brightness requirement (measured in lumens) varies depending on a range of factors, including image size, ambient light, and nits. The brightness requirement will affect the diagonal size of the DMD active array. You can learn more on how to select the right brightness level for your application by reading TI DLP® IntelliBright™ Algorithms for the DLPC343x Controller or watching this video.

  • Brightness vs power consumption, In general, the brighter the projection module, the higher the power consumption (driven mainly by the illumination power). For embedded applications, a target power of 1 to 2 W is typical, while accessory projectors can range from a few watts to tens of watts. In the case of LED illumination sources, efficiency is typically not linear, meaning doubling the power to the LEDs results in less than double the brightness. Finding the right balance of brightness and power consumption is important.
  • Brightness vs size, optical modules can vary greatly in size from a few cubic centimeters in embedded smartphone or tablet applications to hundreds of cubic centimeters in high brightness accessory projectors. In general, projection modules with higher brightness capability are larger in size. A larger illumination source, optics, and DLP DMDs may be used in order to achieve a higher brightness. The power and heat generated by the illumination source increases as the brightness increases. Heat dissipation requirements add to the size if heatsinks or fans are necessary. The size of small, low power DLP Pico systems is driven mainly by the size of the optical module, while the size of larger, higher brightness DLP display systems is driven not only by the size of the optical module but also the size of the thermal solution.
