difference between tft lcd and resistive touchscreen for sale

Touchscreens have changed the way people expect to interact with their devices. When it comes to smartphones and tablets, touch is the way to go. Even handheld game consoles, laptops, and car navigation systems are moving towards touch. Manufacturers of these devices need to give their respective consumers the responsiveness these consumers are looking for. Selecting the right TFT-LCD display to use for different devices is important.

For touch-sensitive displays, two types of technologies are used: resistive and capacitive. The main difference is in how they respond to touch. Mobile phone comparison site Omio indicates that resistive technology is more accurate but capacitive technology is more responsive.

To elaborate on that, resistive touchscreens allow input from fingers and non-finger objects, like a stylus. A stylus has a smaller point than a finger and makes interaction on a resistive screen more accurate. This makes the technology suitable for devices whose applications require high accuracy, like sketching and pinpoint games. Mobile devices that use a stylus typically have resistive touchscreens.

Capacitive touchscreens, on the other hand, offer more responsiveness with better optical clarity and multi-touch performance. They detect more complex finger gestures. These qualities are shown to be more important for general interaction so it’s more dominant in smartphones and tablets, as well as in other devices with small to medium screen sizes.

As you can see, capacitive screens get general usage while resistive screens cater to more specific applications. With this, TFT-LCD module manufacturers, like Microtips Technology, focus on continuously improving capacitive screen technology.

Electronic Design states that many technological advances can be used to integrate touch sensors directly into the display. In some, manufacturers stack-up the touch sensors and integrate the controller with the display driver ICs. These advances allowed thinner and smarter capacitive touchscreens – a trend that you see in many devices today. For example, Windows phones originally worked exclusively with resistive touchscreen technology but later on moved over to capacitive. If the continuous development of capacitive touchscreen technology becomes successful, these screens may soon have abilities they don’t possess at the moment, such as hover support, non-finger support, and many more.

There are types of touch screen，such as resistive touch panel(RTP), capacitive touch panel (CTP), surface acoustic wave touch display, infrared touch screen. RTP and CTP are used more than others. Can you tell the difference between RTP and CTP? If not, you may want to read along.

In resistive touch screens, two very thin layers of material are separated by a thin gap of air. PET film and glass are typically used. Both upper and bottom layers are lined with conductors such as indium tin oxide (ITO). The conducting sides are placed facing one another. So, when you press the screen with finger or stylus, it connects top and bottom layers, creates a change in resistance (an increase in voltage). RTP controller detects this change, and calculates its coordinates, then determines the position of touch.

Capacitive touchscreens, on the other hand, respond directly to the touch of your finger or an input device such as a stylus. On top of LCD panel, lies a thin layer of transparent electrodes. When a human finger touches the screen, some of the electrical charge travels from screen to user. The change of capacitance is then detected by sensors located at screen"s four corners, allowing controller determine the touched location.

Resistive touch screens are effective in a variety of environments. Any object capable of applying force to the screen can trigger a touch event. For example, users wearing gloves can operate RTP with no difficulty.Resistive touch screens work well even when liquids or debris are present on the surface. This makes them especially useful in situations where substances could disrupt the function of other types of touch screens, for example, agricultural equipment, boats and underwater machinery. Due to its mature technology and simple structure, cost of resistive screens is lower.

Supporting of Multiple touches is a clear winner for capacitive touch screens (CTP). Thanks to smartphone and tablet, users are comfortable with using gesture on screen. And capacitive touch screen is what user is familiar with. In more specialized settings, such as multi-player gaming application, capacitiv e touch screens can support more than 10 inputs at a single time. Additionally, CTP needs no calibration and is highly accurate.

Resistive touch display cannot determine the location of a touch if more than one input is present. In terms of visibility, the film substrate commonly used as the top surface in resistive touch screens is less transmissive than glass. This leads to reduced brightness and a certain level of haze compared to touch screens with a top layer of glass. The film layer can also expand or contract based on temperature, which alters the distance between the two layers and affects touch accuracy. Additionally, the film substrates are susceptible to scratches and can start to wear away with repeated use, necessitating occasional recalibration or replacement over time.

Capacitive touch screens depend on variations in an electrical field to operate. While a passive stylus can activate this screen, a non-conductive tool like a pencil can"t. If cost is a top concern for a project, CTP may not align with budget limits. It is a more expensive technology than resistive screens, although it continues to grow more accessible in terms of price as the technology advances and improves.

There are many types of touch panel technologies available in the market, the popular types are we are going to discuss the two most widely used types, and compare resistive vs capacitive touch screen

Projected Capacitive Touch Panel (PCAP) was actually invented 10 years earlier than the first resistive touchscreen.  But it was no popular until Apple first used it in iPhone in 2007. After that, PCAP dominates the touch market, such as mobile phones, IT, automotive, home appliances, industrial, IoT, military, aviation, ATMs, kiosks, Android cell phones etc.

Projected capacitive touchscreen contains X and Y electrodes with insulation layer between them.  The transparent electrodes are normally made into diamond pattern with ITO and with metal bridge.

Human body is conductive because it contains water. Projected capacitive technology makes use of conductivity of human body. When a bare finger touches the sensor with the pattern of X and Y electrodes, a capacitance coupling happens between the human finger and the electrodes which makes change of the electrostatic capacitance between the X and Y electrodes.  The touchscreen controller detects the electrostatic field change and the location.

Projected capacitive supports multiple touches (Multi-touch), so it supports a lot of gestures: Zoom in and out (pinch/spread), scroll, swipe, drag, slide, hold/press, rotate, tap etc.

With the new development, projected capacitive touch panels can support gloved hand touch with different glove materials and touch with water or even with salt water.

Before 2007, resistive technology was the most popular touch panel market.  From its name, we know that the technology relies on resistance. A resistive touch screen is made of a glass substrate as the bottom layer and a film substrate (normally, clear poly-carbonate or PET) as the top layer, each coated with a transparent conductive layer (ITO: Indium Tin Oxide), separated by spacer dots to make a small air gap. The two conducting layers of material (ITO) face each other. When a user touches the part of the screen with finger or a stylus, the conductive ITO thin layers contacted. It changes the resistance. The RTP controller detects the change and calculate the touch position. The point of contact is detected by this change in voltage.

With the fast development of projected capacitive, resistive touchscreen devices market is shrinking rapidly but it is still widely used in some industrial applications because of the following advantages.

The following table shows the comparison of resistive and capacitive touch screens. It is up to your application to select the types of technology to use.

After that, PCAP dominates the touch market, such as mobile phones, IT, automotive, home appliances, industrial, IoT, military, aviation, ATMs, kiosks, Android cell phones etc.

The biggest difference a user will notice between a resistive and a capacitive touch screen is that a resistive touch screen can only detect one touch at a time.

There are many other differences between a resistive and a capacitive touch screens– let’s compare some touch screen properties, and how they are different between resistive touch screens and capacitive touch screens.

Works with glovesYesNoA capacitive touch screen depends on a conductive contact. Your finger works well, or the end of a wrench you are holding . . . but non-conductive objects like a gloved finger or the plastic handle of a screwdriver will not be detected.

InterfaceAnalogDigitalThe interface to a resistive touch screen is typically accomplished with two digital ports and two analog ports of your microcontroller, along with a few lines of code. Typically this interface adds zero incremental cost to the project.

Projected Capacitance takes orders of magnitude more finesse to read it, and so most capacitive touch screens have a dedicated IC bonded to their flexible printed circuit (FPC) to handle the added complexity.

Typically you read of a bank of registers on the IC, one register contains the number of points touched, and others registers follow with X and Y coordinate pairs of each point.

As capacitive touch screen functionality increases and costs continue to come down, you can expect to see many more embedded displays available with touch screens in the near future.

When deciding between resistive and capacitive touch, be sure to consider where as well as how the display will be used. Different use cases call for different touch technology.

Resistive touchscreens use a relatively simple technology. A resistive touchscreen comprises two flexible sheets with an air gap between them. When the screen is touched, the sheets make contact. Then the touch location is calculated based on voltages using and an ADC. Read more about how to implement a resistive touchscreen.

Resistive touchscreens register touches made with a finger (even if gloved), stylus, pencil eraser or anything with an end blunt enough not to damage the screen. Most ATMs, card readers at the grocery store, and older home electronics (think that GPS you bought for your car in 2006) use resistive touch sensing.

Because resistive touchscreens are relatively simple and require only four lines to sense touch, the lines connecting the touchscreen to the microcontroller are often incorporated into the main display tail, meaning only one connection between the display module and the controller are needed.

Capacitive touchscreens are a little more complicated. Capacitive touchscreens work by registering a change in an electrostatic field on the screen when touched with an adequately capacitive object, like a finger. Gloved fingers or a stylus may be used, but they must have conductive materials to simulate a bare finger.

Beyond the methods of obtaining a touch, there are pros and cons that must be considered when deciding between a resistive touchscreen and a capacitive touchscreen.

The following table compares resistive and capacitive touchscreens across a variety of categories. In short, resistive touchscreens are less expensive and work well in outdoor applications, but do not age well (they can get scratched, and become hazy with age) and can only register a single touch. Capacitive touchscreens use a glass top layer so they maintain more of the display’s brightness. Plus, capacitive touchscreens can support multiple touches and gestures. The main draw backs for capacitive touchscreens are the higher cost and lower tolerance of environmental factors.

Contaminant ResistanceHigh. Dirt and moisture droplets do not affect the touch sensing.Low. Dirt and moisture interfere with touch sensing, resulting in registering unintended touches.

Light TransmissionPoor. A new touchscreen cuts light transmission from the display by about 20%. As the touchscreen ages, it can yellow or become hazy, further limiting light transmission.Good. A cap touchscreen cuts light transmission by approximately 10%, or less. Age does not affect the light transmission.

Long Term DurabilityPoor. The flexible material will yellow with ages and is prone to scratches. This will affect readability of the display.Good. The outer surface of the touchscreen is fairly scratch resistant, offering protection to the display.

Touch SensingSingle touch. Some pressure is required to register the touch.Multiple touches detectable. Gestures like swipes and pinches can be supported.

Compare some of our families of displays that include a no-touch, resistive touch, and cap touch version. The 5″ sunlight readable displays, above, start at 1000 nits and drop into the 800s.

Further, consider our 3.9″ bar-type display. Without a touchscreen, this display boasts a respectable brightness of 500 nits. With a capacitive touchscreen applied, the brightness drops to a typical brightness of 400 nits. The brightness with a resistive touchscreen applied drops even further, to a typical brightness of 350 nits.

A resistive touch screen is made of several layers. A capacitive touch screen consists of an insulator coated with a transparent conductor.  Use the table below to determining which type of touch suits your project best.

Selecting the most suitable type of touch screen for your project can improve device functionality and durability, which can mean a significant increase in customer adoption.

This article highlights the unique advantages and drawbacks of common touch screen technology, to help product design engineers make an informed decision.

Resistive touch is a legacy form of touch screen technology that was broadly popular for many years, but has been replaced by capacitive touch for many applications. Currently, resistive touch has a smaller range of common uses, but can still capably address certain needs.

The core elements of a resistive touch screen are two substrate layers, separated by a gap filled with either air or an inert gas. A flexible film-based substrate is always used for the top layer, while the bottom layers substrate can be either film or glass. A conductive material is applied to the inner-facing sides of the substrate layers, across from the air gap.

When a user applies pressure to the top surface, the film indents and causes the conductive material on the top layer to make an electrical contact with the conductive surface of the bottom layer. This activity creates a difference in voltage that the system registers as a touch. The location of this contact is pinpointed on the X and Y axes, and the touch controller then interprets the action. Because physical force is needed for a resistive touch screen to function, it is similar to a mechanical switch.

Resistive touch screens must be calibrated before they are used to ensure accurate and reliable operation. A user must apply pressure to the four corners of the screen, and sometimes on its center, to calibrate the screen with the rest of the system via a lookup database.

Because resistive touch screens interpret physical pressure as a touch, they are effective in a variety of environments using single touch. Any object capable of applying force to the screen can be used with the same result. For example, in applications where end users wear gloves, resistive touch screens offer reliable single-touch functionality.

Since resistive touch screens area actuated via mechanical force, they continue to function as intended even when liquids or debris are present on the surface. This makes them especially useful in situations where substances could disrupt the function of other types of touch screens. For example, on single-touch applications within agricultural equipment, boats and underwater machinery.

Besides the functional advantages of resistive touch screens, price is a common reason why OEMs select this option. In projects where cost is a top concern, companies can use this option to realize savings that may not be possible with alternatives.

The configuration of a resistive touch screen removes the possibility of gestures, such as pinching and zooming, or any actions requiring multi-touch functionality. These screens cannot determine the location of a touch if more than one input is present.

In terms of visibility, the film substrate commonly used as the top surface in resistive touch screens is less transmissive than glass. This leads to reduced brightness and a certain level of haze compared to touch screens with a top layer of glass. The film layer can also expand or contract based on temperature, which alters the distance between the two layers and affects touch accuracy. Additionally, the film substrates are susceptible to scratches and can start to wear away with repeated use, necessitating occasional recalibration or replacement over time.

Capacitive touch screens were invented before resistive touch screens. However, early iterations of this technology were prone to sensing false touches and creating noise that interfered with other nearby electronics. Due to these limitations, resistive touch screens and other options, like infrared touch screens, dominated the industry.

With more development and refinement of controller ICs, projected capacitive (PCAP) touch screens became the preferred touch technology for a majority of applications. For example, this technology is now commonly used on tablets, laptops and smartphones. Though PCAP stands for “projected capacitive (PCAP) touch”, it’s more commonly referred to as “capacitive touch”.

The foundation of PCAP touch screens is an array of conductors that create an electromagnetic field. As a user touches a PCAP screen, the conductive finger or object pulls or adds charge to that field, changing its strength. A touch controller measures the location of this change and then instructs the system to take a certain action, depending on the type of input received.

For a device with PCAP touch technology to acknowledge an input, users simply need to touch the screen. No physical pressure is required, unlike resistive touch screens.

Another key difference from resistive touch technology is that PCAP screens can accommodate a variety of inputs, with different gestures and more contact points instructing the system to take a variety of actions. PCAP touch can support multi-touch functionality, swipes, pinches, and zoom gestures which aren’t possible with resistive touch screens.

The value that comes with recognizing multiple inputs is a clear and positive differentiator for PCAP touch screens. Users can initiate a variety of commands, providing more functionality in devices where this technology is used. Consider how consumers now expect smartphones, tablets, and interactive laptop screens to support actions requiring two fingers, like pinching and zooming. In more specialized settings, such as multi-player gaming applications, PCAP touch screens can support more than 10 inputs at a single time.

PCAP touch screens do not require initial calibration, offering a simpler experience than resistive touch screens. Additionally, PCAP touch screens are highly accurate even as they support a variety of gestures and subsequent actions by the system.

Since their top layer is usually made of glass, PCAP touch screens offer a high degree of optical transmission and avoid the appearance of haze to users. Additionally, the glass top layerprovides improved durability compared to the film top layer of resistive touch screens – even for the largest sizes of up to 80 inches (and growing).

Operation in environments where a PCAP screen may be exposed to liquids or moisture — including conductive liquids like salt water — is possible through specialized controller algorithms and tuning. PCAP technology has evolved to support medical glove and thick industrial glove operation, as well as passive stylus operation.

PCAP touch screens can be customized with different cover lens materials (soda lime, super glasses, PMMA) based on application specific needs. Cover lenses can be ruggedized with chemical strengthening and substrates that improve impact resistance. This can be especially valuable for public-facing applications, like ATMs, gas pump displays, and industrial applications. Specialized films or coatings – such as AG (anti-glare), AR (anti-reflective), AF (anti-fingerprint) – can be added to the cover lens substrate to improve optical performance.

Unlike resistive touch screens, PCAP touch screens depend on variations in an electrical field to operate. While a passive stylus can activate this screen, a non-conductive tool like a pencil can’t.

If cost is a top concern for a project, PCAP may not align with budget limits. It is a more expensive technology than resistive screens, although it continues to grow more accessible in terms of price as the technology advances and improves.

The construction of a capacitive touch screen,mainly to plate a transparent film conductor layer on the glass screen,then add a protective glass to the outside of the conductor layer,plate narrow electrodes on all four sides of the touch screen,a low voltage alternating electric field is formed in the electrical conductor.When you touch the screen,due to the existence of the human body electric field,a coupling capacitor is formed between the finger and the conductor layer,the current from the four electrodes will flow to the contacts,the current strength is proportional to the distance from the finger to the electrode,the controller behind the touch screen can calculate the ratio and strength of the current,then can accurately calculate the location of the touch point.

Compared with the resistive touch screens that are common in the market at that time,capacitive touch screen has obvious advantages,no pressure is needed to generate the signal,while the resistive touch screen is activated by pressure.Second,the capacitive touch screen has a long average life.Third,for the resistive touch screen, the upper film needs to be thin enough to be elastic so as to be bent downward to contact the underlying film, so it is easily damaged.And the covers of capacitive touch screen can be thicker, also have glass protection and have good scratch resistance, which can better protect conductors and sensors.In addition, capacitive touch screen is more durable, not easy to aging, high temperature resistance.Moreover, the double-glass design of capacitive touch screen can effectively prevent the impact of external environmental factors on the touch screen,even if the screen is stained with dirt, dust or oil stains, the capacitive touch screen can still accurately calculate the touch position.the more important thing is,at this time, the touch screen has evolved from an early analog touch screen to a digital touch screen, can achieve multi-touch.

A resistive touch screen is a clear overlay which uses physical pressure to detect touch input. It consists of two layers, a flexible outer layer and glass inner layer, separated by an air gap which is maintained by micro dots. The layer configuration used by this technology can accommodate only single touch events, and reduces the transmittance, or brightness, of the display underneath by 20% to 30%. However, resistive touch overlays are often more light weight than their capacitive counterparts, offer higher precision, and can be activated with ordinary implements, including gloved hands. A resistive touch panel will typically be less durable than a capacitive version, with a scratch hardness value of only 3 and lifespan rating of 1 million touches. However, the versatility of this technology and low cost has made it attractive to industrial applications that require advanced input.

The Resistive touch panel senses a touch by measuring where contact is made on the glass. It is independent of temperature and humidity and simple to integrate independent of a separate controller chip.
