LCD mainly consists of LCD black-and-white screen and TFT color screen. The following mainly introduces the relationship between the manufacturing difficulty and size of LCD black-and-white screen: According to expert statistics, the size and process difficulty of LCD segment code screen have such a rule: the larger the size, the more complex the manufacturing process. The main reasons are as follows:   The larger the size of LCD, the more difficult it is for staff to operate.   The larger the size of LCD is, the higher the requirement of equipment grade is.   The larger the size of LCD, the higher the defect rate of the product.   The larger the size of LCD, the more bad things will appear, such as darkening.

Capacitive touch screen and resistive touch screen are mainly different in touch sensitivity, precision, cost, multi touch feasibility, anti-damage, cleaning and visual effect in sunlight.   Touch Sensitivity Resistive touch screen: it needs pressure to make all layers of the screen contact. It can be operated with fingers (even with gloves), nails, stylus, etc. Support for stylus is very important in Asian market, gesture and character recognition are valued everywhere. Capacitive touch screen: the slightest touch from the surface of a charged finger can also activate the capacitive sensing system below the screen. Non-living objects, nails and gloves are invalid. Handwriting recognition is difficult.   Accuracy Resistive touch screen: the accuracy is at least a single display pixel, which can be seen when using the stylus. It is easy to recognize handwriting and is helpful to operate in the interface using small control elements. Capacitive touch screen: the theoretical accuracy can reach several pixels, but it is actually limited by the finger contact area. So that it is difficult for users to accurately click the target less than 1cm2.   Cost Resistive touch screen: very cheap. Capacitive touch screen: the price of capacitive screen from different manufacturers is 10% to 50% higher than that of resistive screen. This extra cost doesn’t matter for flagship products, but it may deter mid-priced phones.   The feasibility of multi touch Resistive touch screen: not possible unless the resistive screen is reconstituted and connected to the circuit of the machine. Capacitive touch screen: depending

How Does An LCD Screen Work? Answering A Liquid Crystal Display Tech Question #LCD #Tech   You can find Liquid Crystal Display (LCD) technology everywhere: in TVs, computers, tablets, laptops, smartphones, watches, monitors, displays, calculators, cellphones, smartwatches, and many more… but do you know how this awesome tech works? Do you also know that the working principle of LCD is pretty similar to the newer LED backlit based screens (edge LED or direct LED)? So today, we explain how an LCD screen work by looking inside an LCD screen and detailing all of its layers. We will talk about the reflector sheet, the Light Guide Plate (LGP), the Dual Brightness Enhancement Film (DBEF), the diffuser sheet, the prism sheet, the bottom polarizer, the bottom glass substrate (backplane), the Thin Film Transistor (TFT), the Liquid Crystal, the Common electrode, the color filter (RGB), the top glass substrate, the top polarizer, and the top chassis and frame. Understanding how a screen works can be especially handy to know if you like clever technology or to understand if your screen breaks down, and you need to figure out what is going on to repair it… knowledge is power!
