A Campus-Wide Digital Transformation Case Study

For Kwangju Women's University, one of Korea's longest-established women's higher education institutions, the question has never been about adopting technology — it has been about making technology serve teaching, not become a burden to it.

The Challenge: Two Persistent Pain Points

Before digital transformation, two operational problems consumed teaching time across campus:

• In bright classrooms, projector images appeared washed out due to low contrast — students in back rows struggled to see course materials clearly

• Multimedia equipment was scattered: projector, speakers, and control systems operated independently with tangled cables cluttering the podium

• 10–15 minutes of class time were routinely wasted on equipment setup and signal switching

The Solution: Campus-Wide Deployment with QSTECH

Kwangju Women's University partnered with QSTECH to deploy X Wall series All-in-One LED Displays across multiple academic buildings, lecture halls, campus TV stations, and public activity areas — a full digital upgrade covering all teaching scenarios.

Visual Experience Reconstructed: A Technical Path to Teaching Equity

120–220-inch All-in-One LED Displays are installed at the front of lecture halls and large classrooms. Custom-sized to fit each space, these displays use COB and MIP advanced display technologies with 4K ultra-high definition resolution.

The result: Students sitting in the last row can clearly identify annotation details on course materials — eliminating the visibility issues of traditional projectors.

Audio System: Uniform Coverage Across the Room

Built-in 120W six-cavity speakers replaced scattered external speakers. After professional acoustic calibration:

• The sound pressure difference between the front and back rows is controlled within 3dB — imperceptible to human hearing

• Teachers can speak naturally without wearing bulky headsets, and every student — including those in corner seats — receives the same audio quality as front-row listeners

Efficiency Gains: Integrated Design That Simplifies Teaching

In standard classrooms and multimedia rooms with the highest daily usage frequency, the impact of digital transformation is immediately measurable:

Teachers now enter the classroom and use the touchscreen interface to:

• One-tap access to built-in smart teaching applications

• Instant wireless casting via Wi-Fi 6 and dual-system native support

• Hybrid teaching sessions without device configuration

This plug-and-play design eliminates the need for teachers to troubleshoot equipment — attention shifts entirely to teaching and student interaction.

Full Coverage: Technology That Blends with Campus Space

Digital transformation extended beyond standard classrooms to specialized scenarios and public areas.

For environments demanding precise color reproduction and high refresh rates:

• Anti-interference transmission architecture supports recording with professional cameras

• No moiré patterns, no flicker — meets professional standards for campus program production and live streaming

Reception Areas and Public Activity Spaces

31mm ultra-thin die-cast aluminum cabinets with four-sided borderless design achieve a 98.9% screen-to-body ratio — displays that blend seamlessly into walls instead of standing out.

Design benefits:

• Control system and power fully built-in — single power cable eliminates visual clutter

• Daily rotation of campus promotional videos and student artwork

• On-demand access for faculty and student demonstrations and collaboration

• Balance of spatial aesthetics and practical functionality

Long-Term Value: Hidden Benefits for Green Campus Operations

Beyond visible improvements in visual experience and teaching efficiency, the campus-wide upgrade delivers operational value:

• 0.5W standby power consumption keeps displays ready while minimizing energy costs

• Reduced maintenance costs and effort over the entire product lifecycle

Unified Experience Across All Scenarios

From small administrative meetings with dozens of participants to large academic lectures with hundreds, QSTECH equipment provides:

• Unified operational logic across all spaces

• Consistent visual style throughout campus

• A seamless smart campus experience for all faculty, staff and students

Technology has shed its cold, tool-like character — it now runs invisibly through every teaching workflow, supporting Kwangju Women's University's modern smart campus vision.
