Compare Display Types: LCD vs LED
When customers inquire about LCD screens, we often provide them with information about the differences between LCD and LED displays and their suitable applications. Whether you're upgrading an existing control room or starting from scratch, technology decisions are crucial. Among the various components in a control room, the data visualization system for operators holds significant importance. If you're considering a large-scale video wall, it's essential to carefully select the display system. LED and LCD are two popular display types, each with its own advantages and disadvantages. To make the right choice for your video wall, let's step back and examine key features of LCD vs LED displays in the context of the control room.
LCDs
LCDs, or Liquid Crystal Displays, consist of two polarized glass panels with a layer of liquid crystals in between. The liquid crystals have properties of both liquids and solids and can be arranged in a crystalline structure. When an electric current passes through them, the crystals shift, allowing light to create images on the display. LCD panels require their own backlighting system to illuminate the liquid crystals and produce the picture.
LEDs
LEDs, or Light Emitting Diodes, are similar to LCDs but use an array of individual LED pixels for the entire display. These LEDs are grouped in clusters of red, green, and blue and emit their own light to create the desired image.
Initially developed in the 1960s for outdoor lighting and signs, Direct View LED had low resolution and was bright enough to compete with sunlight. However, advancements in technology have led to smaller diodes, making LED video display panels a great option for indoor video walls.
Large LED screens with different pixel pitches are produced by itc for indoor, outdoor, and commercial use. It also serves as an LED system integrator.
Indoor LED Screen
High-end BL0.9/1.2/1.4/1.5/1.6/1.8/2.5, which covers the popular pixel pitches on the market and satisfies the display requirements of diverse application scenes.It doesn't have a noticeable black seam in the splicing because to the die-casting and perfectly joined construction. It can be joined in flat and curved fashion. It features a front- and rear-maintenance-friendly design that is anti-electromagnetic radiation, impact-resistant, dust-proof, and quiet.
Outdoor LED video wall
P3/4/5/6/8/10 Transportation, educational institutions, stations, docks, airports, shopping malls, hospitals, hotels, banks and other public locations all make extensive use of outdoor LED video walls, the newest outdoor advertising media trend. It facilitates media presentation, information dissemination, traffic advice, artistic display, etc.
Accuracy of colour management
Transformation of the coordinates of nonlinear chromaticity
broad viewing angle of 140°/120°
high brightness, high refresh, and high grayscale
LED commercial video wall
The 110-inch, 138-inch, 165-inch, and 220-inch itc Commercial video walls are currently envisioned for use in meeting spaces, conference halls, hotels, art performances, and a variety of other settings. Static and highly dynamic images are fine and lossless when employing normal resolution and display ratio, PWM control technology, low brightness, and high grayscale. No optical splicing, 1920 x 1080 resolution, 16:9 aspect ratio, built-in Android operating system, support for WPS office software, clock, welcome screen, calendar, support for remote control, support for wireless mouse control, built-in one-key power on/off, etc.
LED Advantages
LED panels can be simply tiled together to create a practically bezel-free canvas. Aside from this aesthetic advantage, LED displays are a lively option for control room settings that require to monitor data-driven applications like SCADA layouts because to their brightness, improved colour accuracy, and general refresh rate.
In the end, there isn't a single choice that is consistently superior to the other when comparing LCD vs LED; it all depends on your particular use case. When the time comes to make a choice, you may be confident that you did so by considering your requirements and control room. LCD is probably your pick if direct video feeds and high-resolution image clarity are important. If images and layouts are static or reliant on data
