These touchscreen modules come in several types because the touch detection and user interface functionality vary considerably. Below is a breakdown of the most commonly found types:
These are the most common type of touchscreen modules found today. They work by detecting the electrical charge on one's fingertip when one touches the screen. The 7-inch capacitive touchscreen modules are very smooth and highly sensitive and therefore suitable for very responsive interfaces, as are found in smartphones and tablets. They are very clear and supersensitive to contrast and thus suitable for high-definition display devices.
These touchscreen modules are different because they note the pressure applied on the screen. They consist two layers of plastic between which there are conductive paths. When one presses the screen, the layers touch each other at that point, and the contact is registered. They are very good at detecting touch even with a stylus or gloved fingers. They are, thus, used in industrial applications or devices where durability is a must. The 7-inch resistive touchscreen modules are more affordable, especially where budget constraints exist in the procurement of touchscreen devices.
Infrared 7-inch touchscreen modules use a grid of infrared light beams across the screen. Thus, the touch is detected as one breaks the light beam. They give a good picture with no overlays on the touch sensing technology. The absence of a cover layer on the screen makes it possible to come up with better picture quality than resistive modules that have a cover layer. They are, however, not as accurate as other types, which makes them less common in small sizes like 7-inch screens. These modules are suitable for outdoor applications where durability and resistance to the environment are factors.
Optical touchscreen modules detect touch by using cameras located at each corner of the screen. This method makes it very easy to detect touch but makes the screen quite thick. It provides users with flexibility in using their fingers, stylus, or even gloves. They are good for multi-touch and can also recognize hand gestures. This technology, similar to the infrared type, is not suitable for small screens. However, it is suitable for large displays which are used in kiosks or interactive displays.
The following factors that business owners should consider when investing in touchscreen modules for resale:
As seen above, touchscreen modules utilize different touch technologies. Buyers should stock up on a variety of these modules to suit different customers' needs. For instance, a restaurant may need a resistive module for their point-of-sale system, and a gamer may need a capacitive one for their gaming console.
A 7-inch programmable capacitive touchscreen is designed to be compatible with specific operating systems. One of the most important things is to ensure compatibility with the systems that the prospective clients plan to use. This will involve assessing the external factors that affect the choice of the screens, such as the processing power of the target device and the connectivity options. Modules may be compatible with different types of connections, such as HDMI and USB. Therefore, buyers should look for modules that work well with a number of devices, as this will allow them to appeal to a larger market.
Customers are looking for touchscreen modules with maximum sensitivity and precision. To assess a module's performance, one may read product reviews and test the screens themselves. In today's market, customers prize multi-touch support, as it is essential for many applications for modern mobile devices. Screen resolution is also an important quality to consider, especially for customers who want crisp and clear images on their screens. Also, customers may want screens that are more durable than others, particularly those that are resistant to fingerprints or scratches.
Buyers should consider modules that come with software development kits (SDKs) or have open-source software. This will make it easy for their customers to make interfaces that are custom, especially if they will be used in unique applications. Also, it will be important to check other customizable options for the screen sizes of the modules. Some clients may want screens with additional buttons or changed layouts.
As already touched on above, the 7-inch screens are probably the most popular option for portable devices like tablets. Thus, it is important for business owners to shop for these products in bulk so that they can enjoy lower prices. The profit margin will be larger based on lower prices. It will also be important to familiarize oneself with the warranty and return policy of the supplier to avoid incurring losses on defective products.
The following are the most common applications for these touchscreen modules:
As pointed out, these touchscreen modules are commonly used in smartphones and tablets. They provide good interactive experience on devices as users can use apps, browse the internet and perform all sorts of functions using touch. The screens have a compact size and are therefore applicable in portable gadgets. The programming features allow users to operate their gadgets with customized UIs.
These touchscreens are perfect for controlling machinery and monitoring systems in industrial settings. The ability to program the screen enables workers to create custom interfaces that will display critical data and make it possible to control operations using just a few taps. They are even designed to operate under harsh conditions, thus adding to their durability.
In healthcare, users will find these touch-enabled screens integrated into diagnostic equipment and patient monitoring systems. Touchscreen technology will enable practitioners to interact with complex medical data more accurately and quickly. Further, the modular aspect allows the device to be reprogrammed quickly for use in different medical applications.
They work in infotainment systems and navigation units in vehicles. Drivers and passengers will enjoy controlling music, GPS, and other vehicle settings through a simple touch. The programming touch screen can also be developed to provide different car information systems, thus improving the drive experience.
They use these touchscreen modules in customer service kiosks, ticket machines, and interactive advertising displays. The screens can be programmed to show different content depending on the situation or audience. This makes them very versatile for the advertising and retail industry applications.
These modules have several important functions and characteristics to consider when purchasing or using one. Below are some of the most distinguishing features of these touchscreen modules:
Maintenance is very important in prolonging the life of the touchscreen modules as well as maximizing their performance. Below are some handy maintenance tips:
Capacitive touchscreen modules detect the electrical charge on the fingertip and allow multi-touch. In contrast, resistive touchscreen modules work on pressure applied to the screen and allow touch with fingers, stylus, or gloves.
Yes, they are suitable for industrial applications. They are built with durable materials to withstand harsh working conditions, and their programmable feature enables the creation of custom interfaces tailored for specific industrial tasks.
Do not use any cleaning that contains ammonia or harsh chemicals. They will most probably damage the surface coating of the touchscreen. Just use a gentle cleaning solution for best results.
One should always refer to the manufacturer's instructions to update the module software. Clients should always follow the procedures for refreshing firmware and software as provided by the manufacturers.
Among the most important are display resolution, touch accuracy, screen responsiveness, and power consumption. Also, clients should consider protective features like anti-fingerprint coatings and screen durability.
