49-inch LG 3.5mm LCD Video Wall

Product Introduction

A 49-inch 3.5mm LCD Video Wall offers high-definition resolution and slim bezels for an immersive viewing experience. Ideal for control rooms and digital signage, it provides vibrant, clear visuals with minimal visual disruption, suitable for various professional applications.

Features

Seamless Large Screens with Extreme-Narrow Bezel

The ultra-slim bezel, with its 1.74mm BtoB (Panel Bezel to Panel Bezel), drastically reduces bezel interference and delivers immersive and seamless content on assembled video wall screens.

Image Gap Reduction

The VH7J-H includes an image improvement algorithm that can reduce image gaps among tiled displays when playing back videos. Objects located on the bezel boundaries are adjusted for a seamless viewing experience

Higher Viewing Angle

Large screens are usually positioned higher than human eye level. A wide half-luminance angle (40°) enables effective picture quality for video walls. The viewing angle of the VH7J-H is high enough to display vivid colors throughout the screen without any color distortion.

Wider Viewing Angle

LG IPS panel technology enables stable and smooth control of liquid crystals and allows the screen to be viewed from virtually any angle. Therefore, the VH7J-H captivates the attention of more viewers with lifelike colors, regardless of their viewing position.

Easy Color Adjustment

Depending on the content, the color the temperature of the display can be easily adjusted in increments of 100K using a remote control.

Simple White Balance Adjustment

In conventional video walls, white balance was adjustable only in "full-white" mode, but the VH7J-H allows you to modify each value of grey. scale to achieve more detailed and precise white balance adjustment.

Flexible Content Creation

You can play multiple different videos simultaneously through a web application, and use CSS (cascading style sheet)transition effects to add various animation effects (such as scaling or rotation) to the content. Live streaming is also available, providing the flexibility to organize and diversify content without capacity constraints.

Conformal Coating

Video walls in various places can't avoid exposure to environments with dust, and humidity, which may lead to hampered performance over time. Conformal coating on the major circuit board (power board) significantly reduces these risks from such environments by protecting the video wall from salt, dust, iron powder, humidity, etc

Daisy Chain Capability

A LAN daisy chain allows you to control and monitor video walls and even update their firmware at once. Also, through a UHD daisy chain using HDMI and DisplayPort, you can easily set up a UHD video wall without the need for DisplayPort MST.

IP5x Certified Design

The IP5x Dust-Proof Certification ensures that the product is protected from dust, eliminating the risk of performance degradation.

Is LED or LCD better for Video Wall?

Factors to Consider When Choosing Between LED and LCD Video Wall Technologies

Sawink specializes in video wall solutions, providing secure, TAA-compliant LED and LCD video wall displays along with content management and processing technologies. They assist partners and customers worldwide in determining the best video wall solution for various projects, from mission-critical control rooms to stunning lobby installations and engaging retail displays. When deciding between an LED video wall or an LCD video wall, several factors need to be considered:

Brightness

Brightness requirements depend on the environment and application. In areas with high ambient light, such as rooms with many windows, higher brightness is needed to improve contrast. However, excessive brightness in environments where people work close to the video wall, like control rooms, can cause eye strain and headaches. Conversely, insufficient brightness can result in low contrast, making it difficult to see detailed images and text.

Higher Brightness Displays: Starting with a higher brightness display (700-1000 nits) and then reducing it to fit the ambient light can be beneficial.

Power Efficiency: Running a 700 nit panel at 500 nits consumes less power than running a 500 nit panel at 500 nits.

Increased Lifespan: Lower power reduces heat, extending the life of the LED or LED backlight.

Improved Blacks and Grayscale: LCD panels perform better at lower power levels.

LED Video Walls: Known for high brightness and contrast, LED video walls excel in high ambient light environments, providing superior perceived blacks and high-contrast images.

Seamlessness

Seamless displays are essential for a better viewing experience, ensuring viewers don't notice transitions between screens in a tiled array.

LCD Video Walls: They have borders less than 1 mm, making gaps negligible for viewers more than 3 meters away. However, achieving seamless LCD panels requires professional construction.

LED Video Walls: Truly seamless, LED video walls touch without increasing pixel distance between tiles. Advanced mechanical designs and software features like automatic seam correction enhance seamless image quality.

Picture Quality

Content should look fantastic on your video wall and maintain performance over time.

LCD Panels: Suitable if color uniformity, brightness uniformity, and image quality are not primary concerns, especially for non-24/7 operations.

LED Displays: Offer advanced features for optimizing images and maintaining color and brightness uniformity, making them ideal when image quality is critical.

Viewing Distance

Optimal viewing distance is where viewers can no longer distinguish individual pixels.

LEDs: Calculated by multiplying pixel pitch (mm) by 8. For a 1.25mm pitch, the optimal viewing distance is 10 feet.

LCD Solutions: Achieve smaller pixel pitches (as low as 0.37mm), suitable for close viewing where viewing distance isn't an issue.

Initial Cost vs. Total Cost of Ownership (TCO)

Initial costs and ongoing operating expenses are crucial considerations.

LCD Panels: Lower initial cost, suitable for tight budgets despite shorter lifespans and performance trade-offs.

LED Displays: Higher initial cost but more energy-efficient, with differences in efficiency potentially exceeding 400%.

Complete Solutions

Video walls integrate with content management and processing technologies for a comprehensive solution.

SDVoE Solutions: Enable uncompressed, zero-frame-latency, artifact-free content over 10G networks.

Image Processing: Capable of displaying 4K@60Hz content and synchronizing multiple outputs, crucial for environments like control rooms.

Service and Support

Best-in-class video walls are serviceable from the front end, reducing repair time and downtime. Remote video sources, controllers, and power supplies simplify maintenance and minimize disruption.
