How to Identify the Best LCD/LED Display for You

Introduction

The LCD screens include LCD (Liquid Crystal DIS) displays and LED (Light Emitting Diode) displays, which generate points, lines, and surfaces in a way that current stimulates liquid crystal molecules to form a picture with the back light tube. Compared with the traditional cathode ray tube (CRT), it has a larger volume, a soft picture, no flickering on the picture, and reduces eye fatigue. An LCD (Liquid Crystal Display) is a flat-panel display that uses liquid crystals for its primary operating form. Liquid crystal screens use liquid crystal material as the basic component. Because liquid crystal is between solid and liquid, it not only has the optical characteristics of solid crystals, but also has the characteristics of liquid flow, so it can be said to be an intermediate phase. What is an Interactive Flat Panel Display? An interactive flat panel display (IFPD) is a large format touch screen display. Integrating interactive whiteboard, screen sharing, and touchscreen monitoring, it is ideal for collaborative meetings or interactive teaching environments. At IQBoard, we call it "IQTouch".

How does the liquid crystal realize the function

The liquid crystal screen is based on the liquid crystal material as the basic component, and the liquid crystal material is filled between two parallel plates, and the arrangement of the molecules inside the liquid crystal material is changed by voltage, so as to achieve the purpose of shading and light transmission to display different shades and random arrangement. Subtle imagery. Adding a three-color filter layer between two flat plates can display color images.

What are the advantages of LCD

Liquid crystals usually require the use of low-impedance metal materials, high-performance switching elements, and high-precision processing techniques, so liquid crystals can achieve large-area high-resolution displays. LCD screens are very low in voltage and power consumption, and engineers are very fond of them. The appearance of the liquid crystal is small and exquisite, and the thickness is only 6.5-8mm. The passive display type of liquid crystal has no glare, does not irritate human eyes, and does not cause eye fatigue to a large extent. The LCD screen can make the pixels smaller and maximize the amount of displayed information. The most important point is that the LCD screen has no electromagnetic radiation, which is very safe for the human body. Another point of LCD is that it has a very long service life, because there is almost no deterioration of the LCD, except that the life of the LCD backlight is limited, but the backlight part can be replaced, so the service life of the LCD is very long, and the LCD is applicable to all electronic devices.

Why choose IQ LCD

The decisive factor of the performance of the LCD screen is its panel, because the quality of the panel directly affects the viewing effect of the picture. So to choose a good LCD screen, you must first choose its panel. The LCD panel can determine the brightness, contrast, color, viewing angle and other very important parameters of the LCD screen to a large extent. As a provider of interactive display solutions, we offer IQTouch interactive LED displays and IQBoard interactive whiteboards designed to facilitate personalized learning and collaborative meetings. IQ interactive flat panels deliver 4K UHD resolution for a sharper on-screen display than most projectors. In addition, the 178° wide viewing angle supported by IFP makes it possible for more viewers to see the screen.

In addition, the IQ interactive tablet optimizes the writing function of up to 40 points of touch, and has more gesture zooming and dragging functions than traditional whiteboards. IQTouch interactive tablets have many built-in software integrations such as AI whiteboard, EShare Pro for wireless screen sharing, IQ KitsMemos interactive teaching software or JoinMemos collaborative meeting software, which are pre-installed on all displays. With IQ, you can use LCD products more conveniently and make your life more colorful.

Five suggestions for better use of LCD

1. Adjust the contrast to not lose the details of the picture. The contrast of the liquid crystal affects the light and dark contrast of the character scene, that is, the texture change of the viewing picture. Adjusting the contrast to an appropriate size can improve the viewing experience.

2. Adjust the brightness at any time and make good use of various brightening functions. The brighter the brightness of the liquid crystal, the easier it is for the viewer to find it at a glance. However, the ultra-bright picture is usually traded at the expense of image quality and the life of the display, so in daily use, do not adjust the brightness too high.

3. Don't point and point to avoid scratching the screen with hard objects. The LCD screen is the same as the mobile computer screen. During use, do not put hard objects on it to scratch it,  so as not to leave scratches and affect the viewing effect.

4. The time interval between switching on and off the screen should be more than five minutes. Do not switch on and off frequently, so as to avoid the impact of current from affecting the service life of the LCD.

5. If the power switch of the display screen often trips, you should check the screen body or replace the power switch in time, and check the firmness of the connection regularly, and adjust it in time if it is loose.

Summary

An interactive display is an embedded device that people can interact with using a digital touch screen to give a lively visual presentation and enable the audience to have a good discussion and interaction. And it is an all-in-one machine that integrates collaboration and meeting management functions. Users can connect the interactive flat panel display through their own devices, or use the multi-touch function on the interactive touch screen. When choosing an LCD screen, you need to consider important parameters such as the resolution, contrast, brightness, and presence or absence of dead pixels of the LCD screen. Today, smart tablets not only allow teachers and presenters to share information more clearly like touchscreen TVs, but their touchscreen functionality also provides an engaging experience for viewers. People still use traditional keyboards and stylus to enter options. However, the advanced interactive screen has multi-touch and can recognize up to 20 touch points at the same time, bringing more possibilities and convenience. So individuals can easily and instantly share ideas on a smart digital display panel. Bring everyone's ideas to life by seamlessly sharing ideas through easy collaboration on IQTouch.
