A pixel is a unit that is usually invisible to the naked eye. How can I see the industrial control LCD screen? That is, if you magnify the image of the LCD screen several times, you will find many small dots, which are actually pixels.
A pixel is a unit.
The pixel of the industrial control LCD screen is used to calculate the unit of digital impression. It seems that the photos taken are all the same, and the digital impressions have successive shades. If you magnify the impression a few times, you will see that these continuous colors are actually made up of many small square dots near the color.
Pixels are individual LCD lights.
The LCD splicing unit of the industrial control LCD screen is a full-color screen, and red, green and blue are the primary colors in the color. Because there are many colors to be realized in an LCD screen, red, green, and blue lights need to be made together to form pixels.
Pixels are divided into real pixels and virtual pixels.
In addition, the pixels of the industrial control LCD screen have real pixel display and virtual pixel display. The two techniques are different. The virtual display adopts the virtual pixel technology, that is, the LCD multiplexing technology, the same LCD light-emitting tube can be combined with the adjacent LCD light-emitting tube four times (down, down, left, right combination). Generally speaking, a pixel is a unit. At present, the pixels of LCD screens are basically 1920*1080, while the pixels of some display screens can be as high as 3840*2160. The higher the pixel, the sharper the displayed picture.
Paste with OCA optical glue to protect the screen.
While cover glass can provide protection, if you want to make the product more durable or more protective, such as UV protection, moisture and dust resistance, OCA bonding is more suitable.
OCA optical adhesive is one of the important raw materials for protecting industrial LCD screens. Optical acrylic adhesive is made without a substrate, and then a release film is attached to the upper and lower layers of the bottom layer. It is a double-sided tape without a substrate. It has the advantages of high light transmittance, high adhesion, water resistance, high temperature resistance and UV resistance.
Filling the air gap between the TFT LCD and the top surface of the display screen with optical glue can reduce the refraction of light (light from the LCD backlight and the outside world), thereby improving the readability of the TFT display screen. In addition to the optical benefits, it improves the durability and touch accuracy of the touchscreen, preventing fogging and condensation.
