Smartphone Wi-Fi Analysis
Smartphone, Wi-Fi

Smartphones have many functions. We have talked about four functions in the previous articles (display, camera, audio and touch). This time around, we introduce Wi-Fi testing for smartphones.

4K, Display, UHD

Since TV makers must compete for the attention of customers within retail stores, they usually adjust default settings to display vivid colors. TV makers also apply color-tuning settings that reflect their brand image. In this article, we describe Picture Quality (PQ) testing using vivid color settings.

Allion to Launch DisplayPort 1.4 Receiver Jitter Tolerance Test Service
出DisplayPort 1.4 Receiver Jitter Tolerance

Since 8K displays require faster data transmission speeds and more precise signals, VESA recently launched DisplayPort 1.4, which clearly stipulates the design specifications for HBR3 (8.1 Gbps) signals. In comparison, the previous DisplayPort 1.2 specification only supported transmission speeds up to 5.4 Gbps. Due to the increased bandwidth, DisplayPort 1.4 can support high-resolution 8K video.

VESA has also defined a Compliance Test Specification (CTS) for DisplayPort 1.4. To ensure high-quality end user experiences, Allion Labs, Inc. (Allion) has just recently launched HBR3 jitter tolerance testing. This testing can help product designers locate potential problems prior to product launch by focusing on the physical layer.
