It is one of the most commonly used display screens in liquid crystal displays. TFT stands for thin film transistor, and it is an abbreviation for thin film transistor. Some issues with the TFT screen manufacturing process, such as when there is a noticeable color difference on the screen, can be resolved by following these steps. When the TFT screen is assembled, the color of the screen is different from the original color. During today's presentation, Szmaclight will go over the factors that influence the color difference on TFT screens.

The chromatic aberration of a TFT screen is caused by the different types of glass used by different panel manufacturers, which results in a slightly different appearance.

LCD Panel Process

When glass is cut into pieces, the colors of different batches of glass from different glass panel manufacturers are vastly different from one another after being cut into pieces. Innolux, BOE, AUO, and others are among the most important glass manufacturers in the world at the moment. In addition, the panels produced by each manufacturer are eventually assembled into small TFT screens, which exhibit chromatic aberration due to the manufacturing process.

The chromatic aberration of the TFT screen is caused by the use of different backlight batches on the same screen.

In the backlight, the LED lamp bead serves as the primary component, and it is this component that is most responsible for the ability of the display to shine and display brightly. The RGB color model, which is used to describe the white LED light, is composed of three colors: red, green, and blue. If there is a slight shift in the wavelength of light from the left to right, the LED optics will react, resulting in a slight change in the display effect of the liquid crystal panel as a result of this. The chromatic aberration of the TFT screen will result as a result of this.

The use of different polarizers on the TFT screen results in chromatic aberration on the screen, which is undesirable.

An optical film with the function of generating polarized light, the polarizer is composed of multiple layers of polymer materials and is composed of multi-layer polymer materials. It is made up of multi-layer polymer materials and has the capability of generating polarized light as well as other functions. A liquid crystal screen's surface sheet and negative film are the two most fundamental types of liquid crystal screens, which can be distinguished based on the various applications for which they are used. The polarizer is made up primarily of the polarizing layer, the TAC layer, the adhesive, the peeling film, the protective film, and the reflective film. The polarizer is also made up of the following components:The polarizing film will reflect different colors at different angles, resulting in a different display effect depending on the angle from which it is viewed. So the final results of each production will be influenced by the number of polarizers produced in different batches, as will the polarizers produced with different rotation angles in various batches.

The causes of color difference on TFT screens listed above are the only ones that I was able to identify during my investigation. Everybody, I believe, is aware of the fact that color differences between TFT screens shipped in the same batch are virtually impossible to achieve. When producing small TFT screens, it is necessary to use raw materials from the same batch as well as the same manufacturer in order to ensure that there are no color differences between the different manufacturers' products. So when purchasing TFT screens, it is critical to communicate with the screen manufacturers in advance about the color range and to decide which color range you are willing to accept as acceptable before making the purchase.

Everyone is familiar with industrial-grade liquid crystal displays (LCDs), which are primarily comprised of panels, backlights, cables, and integrated circuits (ICs), among other components. Do you have a clear understanding of how each component was developed? Whenever it comes to the design of industrial-grade LCDs, every component is critical because it has an impact on both the overall structure and function of the device. This afternoon, Kingtech will guide you through the process of learning about the specifics that need to be taken into consideration when designing the layout of an industrial 10.1 inch LCD.

The cable alignment line must be included on the backlight iron frame of the industrial LCD manufacturers in China manufacturers in China in order for it to function properly. Otherwise, the display will not function. A specific location on one side of the cable is recommended for the alignment line of the cable, and it is recommended that the alignment line be silk printed on the backlight using silk screen printing technology.

It is necessary to maintain a specific position distance between the wiring and the backlight accessories in order to prevent the distances from becoming too close to each other and overlapping. A similar consideration must be given to the issue of accessories that are connected to other accessories.

A large number of customers are required to bend the transflective display before it can be shipped to their location. At this point, the model must be bent and packaged in preparation for transportation. The industrial 10.1" tft liquid crystal display cable is designated as a nonadhesive substrate in order to ensure good bending characteristics, and electroless gold plating is required to complete the manufacturing process of the cable.

It is necessary to bend the industrial vatn display cable in order for it to be shipped safely and securely. Keep a close eye on the warping of the industrial 10.1 inch LCD cable for any signs of damage. It has the potential to be dangerous. If the industrial TFT manufacturers cable has an iron frame on the back, the industrial sunlight readable LCD cable must be adhered to the iron frame with double-sided tape to prevent the cable from slipping. Using double-sided tape, both sides of the industrial transflective display cable need to be joined together at the same time. There is no need to attach yellow and black protective paper to the cable at this time. Make sure that there is a certain distance between the iron frame and the industrial VATN LCD cable when installing industrial HDMI TFT display module cables that do not have an iron frame on the back. You should also use a yellow protective paper to ensure that the industrial sunlight readable LCD cable does not become warped during the installation process.

It is especially critical to pay close attention to designs that have a complex structural layout or composition. Hole-to-hole alignment (hole-to-hole on FPC, backlight positioning column to alignment hole on Industrial LCD manufacturer line), line-to-line alignment (Industrial 10.1 inch LCD line etching line to silkscreen line), side alignment, and side alignment with a backlight positioning column to alignment hole are some of the alignment methods currently available.

In order for the industrial sunlight readable LCD line to function properly, the screen printing line, the backlight edge and auxiliary material alignment lines, as well as the reverse folding alignment line, must all be in place and operational.

In order to prevent fraying of the industrial LCD cable, it is necessary to apply an appropriate thickness of double-sided adhesive tape to it. This will have an effect on the bending of the industrial transflective display cable, so it is important to pay close attention to the distance between the two components.

Detail considerations should be taken into consideration when designing the layout of an industrial LCD liquid crystal display. For example, the manufacturer Kingtech Group Co., Ltd. is well-known for paying meticulous attention to the smallest of details. We will take into consideration all of the characteristics of each component, as well as any potential problems that may arise during the manufacturing process, allowing us to avoid risks and reduce the defect rate as much as possible.
