With the continuous development of the display industry, TFT touch monitor stands out. It has many advantages such as high responsiveness, high brightness and high contrast, and has become the mainstream display device on the market. The market of TFT touch monitor is the same as that of other products, and the quality is uneven, so how can we buy a high-quality TFT touch monitor? Today, Top One Tech will introduce you what parameters to consider when purchasing a TFT touch monitor.

1. Resolution

The resolution is usually represented by a product, such as 320×240, 640×480, 1024×768, etc., which respectively represent the number of pixels in the horizontal direction and the number of pixels in the vertical direction. Resolution is a very important parameter, because the resolution directly determines the image clarity of the TFT touch screen. If the size of the monitor is the same, the higher the resolution, the clearer the displayed image, the more delicate the image, and the better the display effect.

2. Color

The most important thing about the TFT touch monitor is the degree of color expression. The color level is the number of colors that the LCD screen can display. Therefore, when purchasing a TFT touch monitor, be sure to observe the effect of color intensity, whether it is realistic, and whether there is a distortion effect.

3. Brightness

The brightness of the TFT touch monitor is mainly determined by the backlight source, and the brightness value is generally between 200 and 250 cd/m2. Just like our mobile phone screen, the lower the brightness, the darker the screen will be, and the higher the brightness, the brighter the screen will be. Although the current level of technology can achieve high brightness, Top One Tech's touch monitor brightness can reach 1000cd/m2, which is suitable for use in outdoor sunlit environments. However, the brightness value is not the higher the better. In the room, if the brightness is too high, it will be very dazzling and hurt the eyes of the viewer. Therefore, the brightness value should be adjusted according to the actual application scene of the terminal device.

4. Visible range

When purchasing a TFT touch monitor, an essential parameter is the visible range. The larger the viewing area, the better, so that the user can view the display from all angles without eye strain. If the viewing range is too small, the user's viewing effect may be very poor from a certain angle, and the displayed picture may not even be clearly seen, which will also cause eyestrain, so it is extremely inconvenient and directly affects the user's visual experience. Therefore, when purchasing a TFT touch monitor, be sure to confirm the visual range of the product.

5. Contrast (contrast value)

The contrast value is defined as the ratio of the maximum brightness value (full white) divided by the minimum brightness value (full black). The higher the contrast ratio of the TFT touch monitor, the more vivid the color of the entire screen, the higher the saturation, and the stronger the three-dimensional effect. If the contrast ratio is too low, the screen display effect of the entire TFT touch monitor is bad, and the colors are not bright, which greatly affects the visual experience of customers.

6. Response time

Response time refers to the response time of a pixel from dark to bright or from bright to dark, generally in milliseconds (ms). Response time determines the ability of a touch monitor to respond to fast moving pictures. The smaller the value, the better, because the faster the response time, the faster the picture changes, and the more perfect the display effect presented. If the response time is too long, the screen will have the feeling of trailing shadow dragging, which will directly affect the user's visual experience.

Another one is the reaction time when touching the screen. It starts from the finger touching the screen, until the screen receives the signal, and then reacts. The faster this process is, the smoother the touch screen receives the signal, the better the user experience.

The above is the parameters to be considered when purchasing a TFT touch monitor.If you have the need to buy a TFT touch screen, you can go to our company's official website to learn more.
