CTOnews.com, December 14, according to Tianma Microelectronics (Tianma) official news, it has developed In-cell active pen (capacitor) technology, innovative realization of mobile phone, tablet, notebook screen multi-terminal "one stroke linkage".

According to reports, Tianma active pen technology integrates Touch Sensor (touch sensor) which supports active pen in the LTPS In-cell display screen by optimizing the panel design. The active pen itself is equivalent to the signal transmission source, and the Touch Sensor receives the signal sent by the pen and finely calculates the (Xgraine Y pen Z) coordinates, which achieves the effect of writing with the pen tip on the Tianma screen, and the line accuracy / linearity and other indicators are more than 50% higher than that of the passive pen.

▲ technology schematic diagram, in the experience of Tianma Microelectronics, Tianma screen can bring users the writing experience of pixel-level touch precision, and the refresh rate of active pen reaches 270Hz. All the test data of active pen technology equipped with Tianma screen are better than the WGP LV1 specification standard of Wacom.

For business, learning and other people, using active pens on mobile phones can quickly carry out shorthand, graffiti and painting operations, and cooperate with Tianma to develop suitable LTPS mobile phone display solutions that exceed 460PPI, which are suitable for travel, mobile office and other scenarios.

When using tablets and laptops to write, annotate documents or design, cooperate with the lightweight In-cell screen developed by Tianma (support high brush above 120Hz and WQXGA HD display), superimpose the advantages of accuracy and refresh rate of active pen, allowing users to complete daily tasks in a clearer and intelligent way.
