don't read novels given below just simple resistive mean you can use through finger and it's very simple just smoothly touch and capacitive means if you use press more on screen to use and open any application and your screen just see scratched http://www.rycom.com.au/capvsres.htm see site

The Analog Resistive touch screen is a sensor consistingof two opposing layers, each coated with a transparent resistive material called indium tin oxide (ITO). The ITO used has a typical sheet resistivity between 100 and 500 ohms per square. The layers are separated by a pattern of very small transparent insulating dots. Silver ink bus bars (~50mW/sq) make an electrical connection to the surface of the ITO at the outside edges, spanning the desired axis of the given layer. Silver ink traces (~50mW/sq) connect the bus bars to an electromechanical connector used for interfacing to the sensor. The cover sheet has a hard, durable coating on the outer side, and a conductive coating on the inner side. When touched, the conductive coating makes electrical contact with the coating on the glass, and a touch is registered by the analog controller. Resistive touchscreens deliver cost-effective, consistent and durableperformance in environments where equipment must stand up to contaminants and liquids, such as in restaurants, factories,and hospitals. Disadvantages of Resistive technology include only 75% optical transparency and the fact that a sharp object can damage the resistive layers. The Analog Resistive technology is perfect for PDAs, web phones, and other handheld consumer applications. Capacitive Touch Screen Technology The touchpad contains a two-layer grid of electrodes that are connected to a sophisticated full-custom mixed signal integrated circuit (IC) mountedon the reverse side of the pad. The upper layer contains vertical electrode strips whilethe lower layer is composed of horizontal electrode strips. The IC measures "Mutual capacitance" from each of the horizontal electrodes to each of the vertical electrodes.A human finger near the intersection of twoelectrodes modifies the mutual capacitance between them, since a finger has very different dielectric properties than air. When a user touches the screen, some of the charge is transferred to the user, and makes the potential difference on the screen.

Resistive Touch Screen Technology Offering excellent durability and resolution, resistive technology is used in a variety of applications and environments.

A human finger near the intersection of two electrodes modifies the mutual capacitance between them, since a finger has very different dielectric properties than air. When a user touches the screen, some of the charge is transferred to the user, and makes the potential difference on the screen. After the panel controller recognizes that, the controller will send the X-Y axis information to the PC port. The advantage is that capacitive technology transmits almost 90% percent of the light from the screen. The superior efficiency gives capacitive better than resistive technology.

A resistive touchscreen panel is composed of several layers, the most important of which are two thin, electrically conductive layers separated by a narrow gap. When an object, such as a finger, presses down on a point on the panel's outer surface the two metallic layers become connected at that point: the panel then behaves as a pair of voltage dividers with connected outputs. This causes a change in the electrical current, which is registered as a touch event and sent to the controller for processing. A capacitive touchscreen panel consists of an insulator such as glass, coated with a transparent conductor such as indium tin oxide (ITO).[11][12] As the human body is also an electrical conductor, touching the surface of the screen results in a distortion of the screen's electrostatic field, measurable as a change in capacitance. Different technologies may be used to determine the location of the touch. The location is then sent to the controller for processing. Unlike a resistive touchscreen, one cannot use a capacitive touchscreen through most types of electrically insulating material, such as gloves; one requires a special capacitive stylus, or a special-application glove with finger tips that generate static electricity. This disadvantage especially affects usability in consumer electronics, such as touch tablet PCs and capacitive smartphones in cold weathers. The debate over resistive vs. capacitive technology in touchscreens is getting old, but still has relevance today. Initially, it was as easy as asking yourself whether you wanted to use a stylus or your finger for interacting with a device. However, refinements in sensitivity of resistive touchscreens in combination with interfaces that are optimized for finger interaction have proved that capacitive touchscreens won't take over the mobile world anytime soon.

capacitive touch screen is more effective than resistive touch screens., it works as follows: the outer screen act as one of the electric plate in the capacitor. when we touch it the capacitance changes due to change in distance between plates. in resistive type, it works by analyzing the change in resistance due to pressure applied.

Resistive touchscreen are comparatively lower in price than active touchscreens. They are built with two flexible sheet coated with a resistive material and separated by microdots or air gaps. when pressed the sheets come in contact and register the contact location. Resistive technology works great with screens mostly used with stylus or any pointing object. But not very efficient in registering the pin point location when used with finger. Capacitive touchscreen on the other hand is a glass surface coated with transparent conductors like indium tin oxide . As the human body is also a conductor, touching the screen with finger creates a electrostatic field, measurable as a change in capacitance. This location is then registered and action.

With a resistive touch,you'll need to apply physical pressure to activate a key,while a feather touch is sufficent for capacitive screens.so obiviously resistive touch screen phones are cheaper.

in simple words capacitive is better and resistive is less responsive and cheaper 2 make

A resistive touchscreen measures the change in resistance between the two layers due to the pressure of touch.A capacitive touchscreen measures the interaction between an electrical signal on a transparent grid above the screen and the user’s finger.A resistive screen can be made pressure-sensitive, so that applications may distinguish between a light and a heavy touch. A capacitive screen just knows “finger present” and “finger absent”.Examples of devices with capacitive touchscreens are the iPhone, iPod Touch, and G1 Android phone. Devices with resistive touchscreens include the LG Viewty phone and the Nokia Internet Tablets.

FIRST QUESTION IS THAT WHAT ARE CAPACITIVE AND RESISTIVE touch screen??: CAPACITIVE TOUCH SCREEN:::: The capacitive touch screen is made up of a glass panel that is coated with a material. The property of this material is that it can store electrical charge. So the capacitive touchscreens basically stores electrical charge. But for good, Human body can also store charge. So, when you touch this screen with your finger, some of these charges on the screen gets transferred to your finger. The oscillator circuits located at the corner of your system will then sense this decrease in the charge on screen and the spot the exact location where touch occurred, and then transfers this specified information to the touchscreen driver software. RESISTIVE TOUCH SCREEN:::: Resistive touch screen, on the other hand is again made up of normal glass panel. However, this glass panel in this case is coated with three layers.Two of these layers being conductive and resistive are kept apart using spacers while the third scratch-resistant layer covers the whole setup.When the resistive touch screen system is running, current flows through these layers. On a finger touch, the two layers get connected and change in electrical field occurs. The system calculates the coordinates of point of contact and passes them to touch screen driver software. COMPARISON:::: 1.MULTITOUCH SUPPORT;;;; available in capacitive screens and notavailable in resistive screens. 2.VISIBILITY:::: Visibility good even in sunlight in capacitive screens while it is poor in resistive screens mostly due to multiple layers reflecting light. 3.SENSITIVITY:::: Highly sensitive to finger touch leading to ease of use and not prone to dust particles in case of capacitive screens while resistive are less sensitive to touch and can be more vulnerable with dust particles! 4.POINTING DEVICE(stylus)::: such devices canot be used in case of capacitive screens because such screens require 5% humidity to get activated while in case of resistive screens these kind of devices can be used... 5.COST:::: capacitive screen are expensive as compare to resistive ones.. 6.ACCURACY:::: resistive screens are more accurate. 7.POWER REQUIRED:::: capacitive screens require less power than resistive ones FINAL VERDICT...capacitive screen scores over resistive one.....

They are different technologies used in touch screen phones. Capacitive is used in high cost phones which is highly sensitive, supports multitouch and have a glossy look whereas resistive is cheaper, more accurate and reliable.

Sir, Capacitive Touchscreen - Capacitive touch sensors are used either as buttons or on touchscreens. They work by sensing the electrical properties of the human body instead of pressure and generally they don't work with a stylus so they don't allow handwriting recognition. Resistive touchscreen - Resistive touchscreens operate by sensing direct pressure applied by the user. It can be activated by pressing it not only with a finger but also with a stylus
