lcd indoor / outdoor display
LCD “Liquid Crystal Display” is a thin, flat display device commonly used in televisions and computer monitors. LCD is also used in the screens of mobile devices (smartphones, tablets, laptops), calculators, digital cameras, digital watches and other similar devices.
How do LCD screens work?
As the term “liquid crystal display” implies, LCD use liquid crystals to turn pixels on and off to reveal a specific color.
An LCD is a stack of 5 layers: the front polarizer, the front electrode, the liquid crystal itself, the back electrode and the back polarizer.
The backlighting used in LCD can be LED (light emitting diode) or CCFL (cold cathode fluorescent lamp) backlighting. Liquid crystals are like a mixture between a solid and a liquid, where an electric current can be applied to change their state so that a specific reaction occurs.
These liquid crystals can be compared to a window shutter. When the shutter is open, light can easily pass into the room. With LCD, when the crystals are aligned in a particular way, they no longer allow light to pass through.

Perfect viewing perspective
The LCD screen has a perfect angle for the viewing image. This means that a person can view an image at a 90-degree angle no matter where they are in the room.

The lifespan of an LCD screen is much longer than the oldest technological televisions. The life cycle of a television is totally dependent on the brightness of the screen and the number of hours it is used.
After COT treatment, the occurrence of yellowing, blistering and delamination caused by extreme temperature will be effectively reduced .
After COT treatment, the occurrence of thickness difference, unevenness and color difference will be effectively reduced.
Exceptional color contrast and brightness
LCD screens have an exceptional color contrast and a constant brightness level. An LCD screen consists of liquid crystal which was not found in previous TVs. This liquid offers a better picture quality.

An LCD monitor is economical in terms of cost and convenient maintenance.
LED have better image quality for two reasons. LED displays work with a color wheel or by using RGB (red, green, blue) colored lights. This will allow the colored lights to produce brighter and more realistic colors. The second reason is that LED can also be dimmed. The ability to dim the backlight of LED displays allows the image to display a true black color by blocking the light and darkening the light to pass in front of the panel.

shooting lines
Reduce the number of scans while designing the display. It is recommended that the number of scans not exceed 16 scans for shooting applications.
Prioritize the reduction of current to reduce brightness, and preset multiple brightness adjustment modes that prioritize the use of current.
Driver IC mode adjustment.
Random scanning.
Rolling black lines
Frame tracking technology to reduce black field waiting time.
Genlock function of the controller to synchronize the LED display with the camera, and fine-tune the phase of Genlock
FRAME MULTIPLICATION to led screen
From the relationship between camera exposure time and LED display frame rate, we can determine the proper combination of shutter angle and frame rate for the most optimal shooting result.
We can support frame multiplication, allowing for expansion of frame rate.

The technology
LCD screens use fluorescent lamps, while LED screens use light-emitting diodes. The location of the light in LED TVs can also be different. LCD screens always have their fluorescent lamps behind the screen. On LED screens, the light-emitting diodes may exist behind the screen on the edges of the screen. The lighting and placement of the lights has allowed LED to be thinner than LED screens. This also means that LED work with better energy efficiency and produce clearer and better quality images compared to LCD screens.
THE ANGLE
Since LCDs are thin, problems such as viewing angle and anti-reflection arise. Compared to LCDs, LEDs offer a better viewing angle. Both LED and LCD are known for the quality of playback and reading.
1. Programming and Intuitive Operation Worldwide
The programming of classical LED Mesh and LED Mesh Curtain can be done using a smartphone, tablet PC or other remote device. The media facade can easily be live controlled from anywhere.
2. Easy installation and Retrofitting
LED Mesh outdoor facade has a simple assembly concept. Though our specially designed clip-technology systems, the LED-profiles and the universal connector system are very easy to install. And, if necessary, they can quickly and smoothly be replaced on location by our team or any Mesh trained person.
3. Brillant Quality
Both the full video-based media facade systems feature an infinite number of colors, a high brightness, resolution and refresh rate for an incredible and creative result on the facade. For both Classical LED Mesh and LED metallic Mesh curtains.
4. Night and Daytime Use
To ensure a 24-hour operation anywhere in the world our Classical LED Mesh and metallic LED Mesh curtain façade are available with a maximum brightness > 11000 nit (cd / m²). At dusk or at night the system can continuously be dimmed, automatically or manually.
5. Homogeneous Appearance
Even though LED Mesh curtains are composed of stainless steel on which are attached LED strips, that make it a massive structure, they have the advantage of having a homogeneous appearance. The LED strips are attached to the reverse side of the wire mesh maintaining the homogenous look of the façade at all times. The Metallic LED Mesh panel is regular. The inconspicuous cabling of each profile is not visible from the outside and with the high transparency of the mesh, the translucent look of the facade is maintained from both inside and outside.The shape and size of the media screen does not have to be the same size as the mesh facade. Since the LED strips are attached to the reverse side of the Mesh wire, they are hidden by it, therefore it becomes invisible. LED Mesh curtain wire are a design piece on their own. Therefore, even when the LED are off, the Mesh becomes an object of decoration and not a simple screen.
