TI DLP Pico 0.23-inch chipset
Reduce the size and power of portable devices
Enables design of HD high-resolution displays

Today, display brightness and resolution have become key criteria for selecting portable and home devices. However, increasing brightness and resolution to high levels is not easy, as it increases the size and power consumption of the device.

Texas Instruments' new DLP Pico 0.23-inch chipset enables the design of high-definition, high-resolution displays while reducing the size and power of portable devices.

The DLP Pico 0.23-inch chipset enables developers to create a variety of next-generation portable displays, such as smart home displays, pico projectors, smart speaker displays, and AR and VR wearable device displays.


Achieving high brightness with the smallest chipset
Even on a compact device, few people want to compromise on display brightness and resolution. Higher brightness allows for clearer HD images, larger projector screens, and better visibility in a variety of lighting conditions, including bright ambient light.

The DLP Pico 0.23-inch family includes the smallest HD display chipset available, enabling the design of ultra-low-power pico projectors that fit in a shirt pocket. The brightness efficiency supports 20-inch to 40-inch displays (up to 200 lumens), and the form factor is less than 78 mm x 78 mm x 15 mm (100 lumens).

Extended battery life with low power consumption
You may have experienced the projector turning off while watching a movie.

DLP TRP 5.4µm reflective technology enables high-efficiency projection applications and extends the battery life of mobile projectors. Because DLP products do not require polarization, they can concentrate all light source energy, resulting in brighter displays without using more energy.

TRP technology features an image processing algorithm called DLP IntelliBright, which can reduce device power consumption by up to 50% or increase brightness by up to 50%. The display controller and digital micromirror device (DMD) consume less than 240mW of power.


HD and qHD display capable
The DLP230KP is currently the smallest chipset capable of HD display projection. The DLP230GP can achieve qHD (960x540) resolution with a chipset the same size as lower-priced HD products.

The following table summarizes the features of the 0.23-inch chipset products.

Resolution	digital micromirror device (DMD)	display controller
qHD (960X540)	DLP230GP	DLPC3432

These chipsets can be used with PMICs, which simplify design by integrating the power management functions required for the DMD, display controller, and LEDs. These three PMICs offer a variety of maximum LED current drive capacities: the DLPA2000 (0.75A), DLPA2005 (2.4A), and DLPA3000 (6A).

Driving and controlling DLP Pico displays requires only a processor supporting up to a 24-bit RGB parallel video interface and I2C. Both display controllers include image optimization features such as 1D keystone correction, dynamic power management processing, and color coordinate adjustment, simplifying display design. TI's high-resolution DMD enables rapid development.
