What is the Real RGB?
The RGB model defines a color by giving the intensity level of red, green and blue light that mix together to create a greater color. To form a beautiful RGB color, the three light beams (one red, one green, and one blue) must be overlaid. The RGB color model itself does not meant by red, green, and blue, but it is the results of blending them together to produce colors that are just relative to the primary colors and our POSEIDON Z RGB has built with 3 colors in each LED that make the final color's spectrum!
The Real 16.8 million Colors
With our new POSEIDON Z RGB, the intensity of each color can vary from 0 to 255, with 0 (zero) indicating the minimum intensity. Gamers can manage the colors (0~255, 0~255, 0~255) with both keyboard and software to produce the stunning colors via the communication with the microcontroller (MCU). The MCU will then send command to the LED Controller to locate each key to deliver the finest color spectrum.
POSEIDON Z RGB uses the newest technology for the microcontroller (32BIT ARM CORTAX-M0) and the 3 LED controllers (16 Bit) to control each Red, Green & Blue light. When all 16 bits are used, one of the components (usually green, see below) gets an extra bit, allowing 64 levels of intensity for that component, and a total of 65,536 available colors. POSEIDON Z RGB uses 8-bit for each Red, Green and Blue color (total of 24-bit) with 256 shades of red, 256 shades of green, and 256 shades of blue, equals to 16.8 million colors, giving you the millions of possible colors!
* (0~255, 0~255, 0~255) is the Red (0~255), Green (0~255) & Blue (0~255) intensity. For instance, (0, 0, 0) is Black, (255, 255, 255) is White, and (255, 0, 255) is Magenta.
Uses the latest 32-bit ARM Cortex-M0 Microcontroller and 16-bit depth LED Controller
MCU (Microcontroller) uses NXP‘s LPC11U3x, designed for 8/16-bit microcontroller applications, offering performance, low power, simple instruction set and memory addressing together with reduced code size compared to existing 8/16-bit architectures. The reason why we used the ARM® Cortex®-M0 processor was because of the exceptionally small silicon area, low power and minimal code footprint of the processor enables developers to achieve 32-bit performance at an 8-bit price point, bypassing the step to 16-bit devices!
POSEIDON Z RGB‘s Red, Green & Blue LED uses Macroblock‘s MBI5042GP LED Controller to control the lighting. The MBI5042GP LED Controller also contains a 16-bit shift register which changes serial input data into each pixel gray scale of output port. Furthermore, the preset current of MBI5042 can be further programmed to 64 gain steps for LED global brightness adjustment. Through MBI5042, all output channels can be built with 16-bit color depth (65,536 gray scales).
