The demand for higher resolution displays is exploding across the market segments from electronics like television, monitors, laptops, and smartphones to the emerging technologies like video and vision, automotive, and AR/VR. The bandwidth requirement for displays increases multi-fold with higher resolution which has been the main driver for development of the latest DisplayPort 2.0 specification by VESA.

High resolution 8k UHD displays for emerging technologies like connected cars, IoT, and AR/VR (Augmented/Virtual Reality) require high bandwidth to support the high-resolution transmission. MIPI DSI is the widely used display interface, but the bandwidth provided by PHY layers isn’t sufficient enough to support the high-resolution displays; therefore, a compression technique like DSC (Display Stream Compression) is required. One of our recent blog discussed about DSC 1.2 in HDMI 2.1 – High Resolution Displays for Mobile, TV, PC and Automotive Enabled by DSC 1.2 in HDMI 2.1. In this blog, we will see how DSC 1.2 enables MIPI DSI to support the high-resolution displays for emerging applications.

Getting the best out of available battery technologies continues to be a challenge for mobile design companies. When phones were used for voice only, the battery lasted a few days compared to less than a day in case of smartphones with high resolution screens, cameras, powerful processors, gigabytes of memories and running power hungry software. Consumers continuously demand more features and functions from their mobile electronics and with more functions converged into a single device, it’s becoming extremely challenging for SoC designs to keep up with the exploding bandwidth, advanced integration functionality and low power constraints.

We are capturing our memories in high-definition with the latest multi-megapixel cameras and playing back with the high resolution displays. This has led to a tremendous increase in data transfer and bandwidth requirements between peripherals and application processor in a mobile SoC. It’s challenging to support advanced multimedia features in the mobile phones by integrating megapixel cameras and superior resolution displays at a reduced cost and power consumption.

DSI is a high speed serial interface targeted to reduce the cost of display sub-systems in a mobile device by transferring the data to the display module in real time without storing the data in the device. However this means that the data has to be sent with proper timing information. The most important aspect in verifying the MIPI-DSI is the timing parameters associated with the video frame transmission. I went through this whole exercises with a couple of VIP users and felt that this would be useful to share as it would benefit others in understanding the complexities involved in video frame transmission.
