The control of LCD screen light leakage is a dual project of "source process+assembly specification ": panel manufacturers reduce light leakage from the source through backlight optimization and full lamination technology;
Side entry light source, as the name suggests, refers to placing light-emitting components (usually LED light strips) on the side edges of a liquid crystal panel, and then using a precise optical guidance system to convert the linear light emitted
Structural design of 5-wire resistive touch screen This is a significant improvement to the four wire design, with the core being the separation of the driving layer and sensing layer, greatly enhancing durability and accuracy
The structural design of the four wire resistive touch screen cleverly utilizes two orthogonal ITO resistive films, precise isolation points, and a time-sharing voltage measurement circuit The core idea is to connect circuits through mechanical contact
The main difference between 4-wire and 5-wire models is not just the addition of an extra wire, but the fundamental difference in structure and working principle, which directly leads to significant differences in performance, lifespan, and cost
What are the classifications of resistive touch screens?The core principle of resistive touch screens is to locate
The application of EMI shielding is extremely extensive, and it is an indispensable "invisible guardian " for modern electronic devices From the phone in your pocket to the satellite cruising in space, blocking net technology is everywhere
The working principle of the shielding net (or EMI shielding layer) is based on electromagnetic field theory, which limits electromagnetic interference (EMI) to specific areas or guides it to the ground
The shielding mesh structure of LCD screens is not a single layer, but a "layered composite system " designed to achieve the best electromagnetic shielding effect The core design concept is to construct a continuous, complete,
The shielding mesh (also known as EMI shielding mesh, conductive cloth foam) of LCD screen is a conductive layer or wrapping material used to suppress electromagnetic interference, usually metal wire mesh, conductive cloth, conductive foam or metal foil,
The working principles of resistive touch screens and capacitive touch screens are fundamentally different, resulting in their completely different characteristics, experiences, and application scenarios
Capacitive touch screens are a standard feature of modern consumer electronics products such as smartphones and ta
Simply put, the core principle of resistive touch screens is "pressure sensing" It determines the position of th
IPS LCD screen (In Plane Switching) is a mainstream mid to high end display panel, with core advantages focused on wide viewing angle, accurate color, and balanced experience However, it also has inherent shortcomings such as power consumption and cost
There is no absolute "better " between IPS and TN LCD screens, depending on your usage scenario TN screens are "e-sports specific ", while IPS screens are "versatile and practical ",
AU s LCD screens have significant advantages in technology and reliability, especially suitable for positioning in the mid to high end market and industrial applications of trade businesses
The development of TFT LCD has moved from the laboratory to the global industry, driven by material innovation, process improvement, and application expansion Despite facing challenges from new technologies such as OLED
TFT LCD is like a full-color television, capable of displaying rich and realistic dynamic images and countless colors A monochrome screen is like the screen of an electronic calculator or watch, which can only display fixed numbers, symbols
Black and white LCD screen is a display technology that focuses on functionality and practicality It is not a "low-end version " of color screens, but the optimal solution for specific scenarios with extremely high cost
TFT LCD is a type of "liquid crystal display " that uses "thin film transistor " technology to enhance performance It can be said that the vast majority of LCD screens we see in our daily lives are TFT LCDs
