Which tablets have resistive screens

At the moment, if you buy any branded Tablet PC above Rs then it has obviously capcitive touch screens which perform well upon swipe the touch than resistive one. Other than resistive touch screen and its issue in low cost Tab PC, we need to observe its specification per requirement. The following brand have mostly capacitive touch screen which performs well without any issue on swipe. Submit New Thread. Follow Us. There are workarounds with capacitive screens but the reality is that they are poor solutions.

Capacitive pens are either blotter-style only, or very inaccurate and with varying efficiency in contact. Environment can make a difference, particularly if that environment is hazardous. If the screen is not inherently IP protected and any sort of transparent cover is placed over the screen for example as part of a protective case then you will require a resistive screen. Pressure can easily transfer through various layers, but the electrical interference of your finger necessary to interact with capacitive screens is easily impeded.

For example some screen protectors, especially higher quality ones with transflective qualities will interrupt the mechanism that capacitive screens rely upon and the two are therefore not compatible. In some ways the most important question is regarding the function of the tablet.

Business use of technology is always different from consumer usage and therefore it's important to identify exactly what the tablet will be used for and specifically what the user must do to achieve it.

These are questions you must ask and answer frequently testing against the previous questions. Although the consumer market has exhibited a trend of capacitive screen mobile devices, resistive screen technology remains very much in use and is frequently preferred by business users. Where capacitive touchscreens suffer is with accuracy. This may be unnoticeable 'all-thumbs friendly apps of the modern smartphone which center around swiping gestures and for zooming in and out of web pages.

But these consumer-orientated functions rarely matter to businesses that would prefer greater accuracy. To quantify this, technically speaking resistive is more accurate than capacitive due to the sensor spacing.

With a capacitive screen you cannot achieve a fine-tip contact such as you would expect from a pen. This is why capacitive styli are typically 5mm or so in diameter and in many cases like a bingo blotter.

If your application is straight forward button activation then this may not present an issue but for most uses, especially signature capture and any interface akin to the controls common within the Windows GUI then resistive is a more comfortable choice. Where businesses do not have a specific requirement for resistive screen touch technology, capacitive touchscreens provide a solution that offers both a familiar interface for users and an easily accessible means of interfacing with simple finger control.

Infrared touchscreens use an array of infrared LED emitters with respective photo detectors around the perimeter of the screen. Essentially the screen is surrounded with horizontal and vertical beams enabling the sensors to accurately detect the location of touch.

A major benefit is that it can detect any input and because the sensors surround rather then fill the screen the longevity and durability is very high.

Of course the optical clarity of the screen is also greater because no sensor layer or conductive layer lies between the user and the actual display element. Infrared touchscreens are generally used in outdoor applications, point-of-sale and other environments where multiple occasional users are involved, or anywhere where the pros of the technology offer a significant advantage. Active digitizers are an input method most commonly associated with an input tablet and pen pair.

The 'tablet' in this description is simply that and does not embody a visual display; rather it is a flat surface on which to use the connected pen.

Classical use was for digital artists to have an input method most akin to using a pen or brush. However this input method can be used in conjunction with a display surface so that the pen input is directly on top of and interacting with the display elements below. Resistive touchscreens can be used by gloved fingers, pens, styluses, prosthetic appendages — anything that can apply the necessary light pressure to the screen.

They are extremely unlikely to be susceptible to any false inputs, since it is necessary to touch the screen to make an input. They also work well even when wet, dirty, oily, or dusty — circumstances that may prevent a capactive touchscreen from being used.

There are a number of other touchscreen technologies from the past and just now emerging — some of them you probably once interacted with, and others you probably will in the future. Technologies like Microsoft PixelSense Surface have a chance to revolutionize what a computer is and how we interact with it.

But in the meantime, these two technologies are, and will continue to be, the dominant methods. For your own product, consider how individuals will interact with it. Will they be indoors, or out in the elements? Will they need to wear special or protective gear while using it? If it does not pinch and zoom, or it responds to a stylus it is probably resistive. Thanks for the reply, I will try that when it arrives in the morning, it seems a pity that they did not give both a different product number though, making it a bit easier for buyers.

Thanks again. Mar 26, 38 4. One other thing, the Witstech tablets are shipped in a generic box without a specific model number. If the ebay seller includes the box, it will have "A81" printed on it.

All of the Witstech tablets are identified as an A81E. Many of the Chinese tablets do not update their model numbers on their ROMs. I learned this from my experience with the Sylvania tablets. The seller claimed it was new, but on peeling away the re-applied screen protector, I can see many swipe marks, no doubt from the sellers frustrated attempts to interact with the tablet.

Any advise welcome please, or it's going back. From what you have posted, I'd send it back. From what I have read on the Merimobile website, the "G" model came in both resistive and capacitive versions. Sounds like this is the resistive version with possibly the Mhz cpu.
