A touchscreen is a type of screen used in computers, tablets and mobiles which can be used by using with fingers or a stylus pen instead of using the traditional mouse and keyboard. There are two types of touchscreens, resistive touch screens and capacitive touch screens, both differs on the layers of sheets or composition they are made and their sensitivity and reaction to pressure or touches. Resistive touchscreens can only register one touch at a time while the latter can detect more than one press a time. Though with these differences both touch screens are widely used in various devices globally. Through continuous innovation and technology, resistive touchscreens which are considered less efficient than capacitive screens are now developed and combined with other technology to provide a more practical and affordable concept for touchscreens.
What is a TFT touchscreen display and where is it used?
Thin Film Transistors (TFT) technology has been introduced to touchscreens. It is a technology that uses liquid crystal display which improves image quality of screens by offering a wider range control over colors and images it shows. It works by controlling the brightness of red, blue and green subpixels through transistors for every pixel on the screen. TFTs and resistive touchscreens combined is widely used in computer monitors, laptops, tablets, media players and mobile devices. The use of TFTs and resistive touchscreens offers a thin, lightweight display for a device. While the innovated combination of TFTs and touchscreens specially TFT resistive touchscreens seems efficient for every devices, there are still different pros and cons concerning the combined technology.
TFT capacitive touchscreen versus TFT resistive touchscreens
The main advantage of TFT resistive touchscreen among other types of touchscreen is the improved color, contrast and image quality displayed on the screen. It can also be used with any surface such as stylus pen, gloves and etc because it needs pressure. The precision of every touch is accurate which is effective for handwriting recognition and other function. The manufacture of TFT touchscreens are also said to be relatively cheaper than other forms. With all of these advantages, TFT resistive touchscreens also comes with a few disadvantages. Though the display is more appealing due to the TFT technology, the characteristic of resistive touchscreen to react with pressure and single touch only make it less desirable. Application of greater pressure in order to function is one of the greatest down point for these type of screen. It doesn’t also allow multi touch function which is now more common in every devices. They also have lower shock resistance making it more prone to breakage and tends to get worn out faster. It also consume more power thus battery consumption is high. And since it has cheaper manufacture rate, TFT resistive touchscreens can be only used for low end or basic cellphones.
What is the future of TFT touchscreen devices and touchscreen TFT PC systems?
TFT resistive touchscreens used widely in different devices improve efficiency in such a way of improving display and quality of every screen it was used to. Wider range of colors and contrasts provide user a much appealing resolution and view in their screens. TFT screens also comes in various screen sizes ranging from 2.4 to 7.0 inches giving the user and manufacturer a wider choice of screen display sizes. The combination of TFT and resistive touchscreens greatly improves efficiency in different industry particularly in the gaming and smartphones area by its numerous advantages and benefits it can offer. Resistance touchscreen overlays continually improve through breakthrough in innovation and technology.
