VESA Unveils New Compliance Test for Automotive Display Standards
Enhancing Automotive Display Standards with VESA's New Test Model
At an exciting exhibition event, the Video Electronics Standards Association (VESA) has released a revolutionary Compliance Test Specification (CTS) software model. This model is a game changer for the automotive display industry, designed specifically to enhance the implementation of the DisplayPort Automotive Extensions (DP AE) specification. With more than 500 functional safety and security compliance tests, the new Linux C-model will enable silicon manufacturers to develop and test components such as electronic control units (ECUs) and timing controllers.
Unveiling Cutting-Edge Technology at Display Week
VESA is set to showcase innovative FPGA-platform demonstrations at the upcoming Display Week Expo, providing attendees an inside look at how the new CTS C-model is facilitating the validation process for automotive displays. These demonstrations will feature inputs from renowned tech leaders like MediaTek, emphasizing collaborative efforts to push the envelope on automotive display safety standards.
Importance of Safety and Security in Automotive Displays
As the demand for advanced and connected vehicles grows, so does the need for sophisticated display interfaces. Cars are equipped with an increasing number of high-resolution displays that deliver vital information to drivers. Traditionally, vehicles have relied on DisplayPort or Embedded DisplayPort (eDP) to transmit video data from the main ECU to these displays. However, prior to the introduction of VESA’s DP AE standard, manufacturers struggled with ensuring the integrity of the data sent to the display, which is crucial for operational safety.
Key Features of the DP AE Specification
The DP AE standard not only supports uncompressed video but also accommodates compressed formats and Multi-Stream Transport (MST) capabilities, allowing for the connection of up to 16 displays. An important aspect of this standard is its capacity to fulfill ISO 26262 ASIL-D requirements, setting a new benchmark for electronic safety integrity in automotive applications.
Furthermore, VESA's innovative approach integrates additional safety and security protocols into the existing DisplayPort standards. This incorporation includes mandatory functional safety profiles and utilizes advanced cyclical redundancy check (CRC) methodologies for ensuring that every frame of video data is accurately transmitted without loss or repetition.
Security measures built into the DP AE standard provide authentication to prevent unauthorized access and maintain the integrity of video data throughout its journey from the ECU to the display device.
Industry Leaders Speak Out
James Goel, a VESA board member and the lead on DisplayPort Automotive Extensions, shared insights on the importance of the new specification. According to Goel, "The automotive industry requires advanced, safe, and secure display interfaces that meet ISO 26262 ASIL-D standards. VESA's DisplayPort Automotive Extensions specification directly fulfills this critical need, enabling faster integration into automotive displays."
Brian Turner, president of BTA Design Services, echoed the sentiment, highlighting the importance of collaboration in pushing the technology forward. "We are excited to be at the forefront of technology innovation, collaborating with VESA and its member companies to develop cutting-edge display technology for the automotive sector. Our focus on ensuring compliance and standards adherence is vital as we prepare for silicon deployment in upcoming years."
