Display controller connects GPUs in clamshell mobile devices
A four-lane DisplayPort 1.4 input and four MIPI lanes for a single panel are combined in the SlimPort ANX7580 DisplayPort to MIPI-DSI display controller by Analogix Semiconductor.
The ANX7580 connects to graphics processing units (GPUs), both embedded and discreet, and to MIPI displays used in dual clamshell display applications. It offers support for DisplayPort and embedded DisplayPort (eDP), Arm, x86 and other computing architectures, high-bandwidth digital content protection (HDCP) support (e.g. video content protection and hi-fi audio). There controller is provided in a small (4.4mm2) footprint and has a low power architecture, drawing less than 150mW, confirms Analogix.
There is also a turn-key reference design to speed time-to-market.
Customers can use the ANX7580 to create differentiated dual screen applications to satisfy the most extreme multi-taskers, observed Michael Ching, vice president of marketing at Analogix. “One can open independent applications on either screen or extend an application across both screens. Gamers can use one screen as a control pad, while multi-taskers can work with two apps simultaneously,” he explained.
“An advantage of this form factor is that the dual screen accessory can be put on when needed and slid the phone out of when not,” he added.
The ANX7580 is in mass production now.
Analogix Semiconductor has announced that its SlimPort ANX7580 DisplayPort to MIPI-DSI display controller has been implemented in LG’s V60 ThinQ and the Dual Screen. It is also used in handheld PC gaming devicesAbout Analogix Semiconductor
Analogix Semiconductor designs and manufactures semiconductors for the digital multimedia market, from portable devices such as smartphones, notebooks, and AR/VR head mounted displays, to large, high-definition TVs and high-end graphics cards. Analogix provides end-to-end interface connectivity semiconductors for DisplayPort under its SlimPort brand, including high-speed signal conditioners, and an industry leader in display panel controllers, such as low-power, high-speed timing controller solutions. The DisplayPort standard is a packetised digital interface for high-resolution video and audio that was developed by the Video Electronics Standards Association (VESA). SlimPort branded products comply with DisplayPort, Mobility DisplayPort (MyDP), and DisplayPort Alternate Mode over the USB Type-C connector.
Analogix claims that its display panel timing controllers are the world’s lowest power, smallest packaging and proprietary image enhancement to produce more accurate colours, thinner bezels and smoother frame rates on the latest high dynamic range (HDR) panels.
