Adapt to the various situations of capacitive screens.

• The standard capacitive screen adapts well.

capacitive touch displays produced by most regular manufacturers and produced in accordance with industry specifications have excellent compatibility with capacitive stylus. Tablets and smartphones under well-known brands such as Apple and Samsung have their capacitive screens that have been strictly adjusted, and the stylus can respond accurately and smoothly when approaching, with smooth writing and drawing and coherent lines, which can meet multiple needs such as note-taking, illustration drawing, and accurate clicking. For example, Apple Pencil and iPad series products are sensitive to pressure, and the changes in the weight of pen strokes are faithfully reflected on the screen, making the writing experience close to real paper.

• The special process capacitive screen has hidden dangers of compatibility.

In order to pursue the ultimate display effect, lightweight, portable and other characteristics, some capacitive screens use special processes or materials, which are not well adapted to capacitive stylus. Some ultra-narrow bezel design capacitive screens, the capacitive sensing layout in the corner area is compact, and when the stylus is close to the corner, it is easy to have induction failure and frequent false touches; There is also a high-resolution flexible screen, although the bending performance is superior, but due to the flexible material interferes with the capacitive signal transmission, resulting in the positioning deviation of the stylus and the intermittent handwriting.

• Inferior capacitive screens have poor compatibility

The capacitive screen equipped with low-cost and inferior electronic products on the market has rough process and poor quality capacitive sensing components. This kind of screen itself has low touch accuracy, and the touch operation is often stuttered and drifting, and when paired with a capacitive stylus, it is either completely unresponsive, or the handwriting is messy, and the command execution delay is serious, and it is almost impossible to use the stylus to complete complex operations normally.

• Screen surface factor interference.

Whether the surface of the screen is filmed and the coating material also affects the use of the capacitive stylus. Ordinary high-permeability plastic film, which has little impact on the stylus; However, functional films such as frosting and anti-peeping change the capacitance distribution and electric field uniformity of the screen surface, weaken the signal reception of the stylus, resulting in reduced operation sensitivity and jerky writing. Some screens come with anti-fingerprint and anti-oil coatings, which will form a capacitive barrier layer when the process is poor, and the command transmission will be blocked when the stylus is tapped, sliding, and seriously affecting the use experience.

In summary, capacitive stylus does not fit well with all screens. Although it is specially designed for capacitive touch screens, it is limited by many factors such as the process level, design characteristics and surface condition of the capacitive screen, so before choosing to use a capacitive stylus, it is necessary to fully consider the specifications and actual touch performance of the target screen in order to obtain an ideal control experience.
