LCD screens can be seen everywhere in our daily lives, from small screens on mobile phones and watches to large screens that play videos in the center of city squares. They are widely used. So how do we choose an LCD screen? Next, the Ruxin editor will teach you how to purchase from the following aspects:
1. Resolution
The resolution is generally represented by a template: * * * X * *, which represents the pixel data in the horizontal and vertical directions, respectively. The high or low resolution will directly affect the image display clarity of the LCD screen. When the display screen size is the same and the resolution is high, the displayed image will be clearer and more realistic, and the effect will be more suitable for viewing.
2. Brightness
Depending on the scenario you are using, the brightness of indoor LCD screens is generally around 200-300cd/m2. If used outdoors, it is best to choose a high brightness screen with a brightness of 500cd/m2 or higher. The higher the value, the higher the brightness.
3. Contrast
Contrast will affect the color brightness of LCD screens. As the contrast value of LCD screens increases, their colors will become more vivid, saturation will increase, and the sense of three dimensionality will also increase; When the contrast is insufficient, the displayed image will greatly affect the visual experience of the viewer. A typical display has a contrast ratio of 300:1. For better displays, you can choose a ratio of 600:1 or higher. The higher the contrast, the clearer the image.
4. Visual angle
This is one of the essential parameters for choosing a LCD screen. The larger the viewing range, the better. When the range is large enough, the display screen can be viewed from various angles and every detail in the screen can be appreciated. However, when the range is too small, the viewer's visual experience will be limited. At present, the viewing angle of LCD screens is generally above 140 degrees, and Shenzhen Nuxin Electronics can achieve above 200 degrees, which can meet the needs of most people.
5. After sales service
For LCD monitors, even if you choose a large brand product, there may still be some unsatisfactory situations, so after-sales service is particularly important. Generally, manufacturers have a 1-3 year full free warranty service, and it is important to understand it clearly before purchasing. Shenzhen Ruxin Electronics Co., Ltd. has professional pre-sales and after-sales services. Welcome to inquire.
