The Future of LED displays:
Advanced Video Processing
Deepsky is pioneering the future of LED displays with the industry's first end-to-end video processing solution. We design and manufacture cutting-edge IC LED drivers, screen controllers, receiver cards, and a precision calibration camera, setting a new standard for image quality.
Our unified technology transcends the limitations of multi-vendor solutions, achieving unmatched image quality with high brightness, fast refresh rates, unmatched color accuracy, extended grayscale, and exceptional reliability.
Today's LED display manufacturers, regardless of whether they produce mini/microLED, COB, GOB, IMD, or SMD displays, typically rely on different third-party vendors for screen control and LED drivers. Yet, these very components critically determine the image quality—brightness, refresh rate, color uniformity, color fidelity, grayscale—and ultimately, the overall viewing experience and screen reliability.
Deepsky is disrupting this model. We offer the industry's first comprehensive image processing pipeline for fine pitch LED displays, featuring:
Deepsky Smart LED driver GEMINI: the first LED driver with Variable Current Technology (Deepsky patent US11,361,707, CN201880098920.8) delivers finer grayscale (19-bit), exceptional brightness (2,500+ nits on small pixel pitch displays), true HDR, ultra-fast scan rates, and low power consumption.
Deepsky screen controller and processing engine HUBBLE: the best GPU-based video processor in LED displays. It constantly optimizes LED control parameters based on individual LED performance, non-linearity, local temperature... ensuring an optimal viewing experience for both human eyes and cameras.
Deepsky Receiver Card GGW_Neo: this compact, robust board serves as the gateway between GEMINI LED drivers and the HUBBLE screen controller. GGW_Neo supports Ethernet Level 2, enabling video distribution between the controller and LED panels using standard, scalable, and cost-efficient Ethernet switching equipment.
Deepsky Software controller and human interface: this modern web-based tool allows for intuitive configuration and control of your displays from any device, both locally and remotely.
Deepsky calibration platform Orbital Cam, arguably the most accurate LED pixel brightness and color measurement instrument in the industry. It's built on a unique scientific model that analyzes each LED chip in your display.
Central to Deepsky's video processing pipeline is the ability to accurately change the LED current in GEMINI, our patented IC driver (US patent US11,361,707, CN201880098920.8).
From 0 to approximately 50 nits, HUBBLE, Deepsky's GPU processor, instructs GEMINI to operate at its lower LED current setting (around 0.156mA). This results in low-amplitude LED light pulses, allowing the Delta Sigma linear modulator to achieve a very fine control over the LED brightness.
Once the maximum brightness achievable at this lower current is reached (around 50 nits), HUBBLE progressively increases the current instructions for the various GEMINI drivers on the screen. This leads to a gradual increase in overall display brightness.
The above chart illustrates how combining Variable Current and Delta Sigma modulation creates a non-linear brightness control. This approach aligns perfectly with the human eye's heightened sensitivity at lower brightness levels.
By combining a linear Delta Sigma modulator with the 16 available LED current levels, we achieve an effective dynamic range equivalent to a linear 19 bits.
