The On-Screen Display (OSD) is a crucial interface through which users interact with display products, encompassing key operations such as settings adjustments, menu navigation, and feature selection. As products are sold globally, display devices must support multiple languages to ensure users from different regions can easily understand and operate the device. However, any errors in OSD language display can directly impact user experience and brand trust—and may even result in product returns or customer complaints. Therefore, OSD language testing is an indispensable step in the development of display products!
Common Challenges Faced by Manufacturers: Manual Testing is Time-Consuming and Inaccurate
Most manufacturers still rely on manual methods for OSD language testing, but often face the following three major challenges:
1. High Expertise Required：
Language recognition skills and UI testing experience are essential to identify display anomalies and formatting issues.
2. Time-Consuming and Inefficient:
Multilingual testing requires manual verification of each language’s display content, leading to long testing hours and delayed product launches.
3. Inconsistent Accuracy:
Manual testing is prone to fatigue and subjective judgment. When testers are unfamiliar with a language, misjudgments and omissions are more likely, reducing overall test quality.
Customer Background and Real-World Challenges
The client in this case is a well-known display manufacturer that recently launched several new monitor models. Despite completing internal OSD language testing before market release, they still received multiple customer complaints, including:
- Grammatical errors
- Poor localization
- Garbled or corrupted text
During internal testing, checking just one language could take over 4 hours. For models supporting 8–10 languages (sometimes up to 20), the human resource burden became overwhelming. Even when test reports marked results as “pass,” complaints persisted post-launch—clearly revealing a mismatch between effort invested and actual outcomes. As a result, the client turned to Allion for a more efficient and quality-assured testing solution.
Allion’s Solution: Accelerated OSD Language Testing with DisplayAI Automation
Upon realizing their internal methods were insufficient, Allion’s AV consulting team immediately recommended the DisplayAI Test Solution—an automated OSD language testing solution.
This AI-powered automation solution replaces time-consuming manual operations. By simply preparing string data files for each language and writing test scripts based on the OSD menu tree, testing can be launched quickly. This drastically reduces setup time and ensures 100% accurate test results.
As illustrated above, manually testing one language traditionally takes about 4 hours. With Allion’s automated OSD language testing, the initial setup is only required once. Afterward, adding a new language requires just 0.5 hours of manual configuration, with the rest handled by automation. The total testing time drops to just 2 hours per language.
Compared to manual methods, Allion’s DisplayAI automated testing can save approximately 88% of manual effort and shorten overall testing time by 38%! In addition to saving time and manpower, the solution also minimizes human error caused by fatigue or oversight, ensuring consistent and reliable test quality.
