Which of the following describes a disadvantage of resistive touch screens?

• A. They are generally more expensive
• B. They do not support stylus input
• C. They tend to have poor visibility in sunlight
• D. They have better durability than capacitive screens

Answer: (C)

A resistive touch screen operates by using pressure to detect touch inputs, which can lead to some disadvantages, one of which is visibility in bright conditions, such as direct sunlight. When exposed to intense light, the screen's layers can reflect light and create glare, making it difficult to see what is displayed. This drawback arises because resistive screens are made of multiple layers, and the light can reflect off these layers, reducing clarity and making it hard to interact with the screen. In contrast, capacitive touch screens, which sense the electrical charge from the human body, usually perform better in bright conditions, as they do not have the same reflective properties and can remain more visible under such circumstances. This distinction makes the visibility issue a significant drawback for resistive touch screens, especially in outdoor or well-lit environments.
