Transparent rectangle on screen8/30/2023 ![]() The optical under-display fingerprint sensor, which recognizes a fingerprint using the difference in light reflected at the finger ridge and valley areas, has an issue in recognizing dry fingers, which cannot make uniform and consistent contact with the surface of the sensor cover layer 12, 13. However, in some cases, these sensors may not work as satisfactorily as conventional fingerprint sensors. Among them, optical and ultrasonic sensors are used in some smartphone models because they can be placed under the display and do not interfere with display imaging, even though they are relatively bulky and costly. Typical examples include capacitive, optical, and ultrasonic fingerprint sensors. Various types of sensors that can recognize fingerprints on display screens have been developed 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11. However, the most convenient and intuitive location of the fingerprint sensor is on the front face. ![]() For this type of smartphone, fingerprint sensors, formerly located under the home button, have to be positioned on the back or side of the smartphone. By applying the selected sensor pattern and circuit driving by block, fingerprint sensing on a display is demonstrated with a prototype built on a commercial smartphone.įull-screen smartphones with extremely thin bezels without physical buttons on the front have become the mainstream in the smartphone industry in recent years. ![]() As the selected sensor pitches are too small to detect capacitance variations, three unit patterns are electrically connected to obtain a unit block generating a larger signal. The range is narrowed for an experimental evaluation, which is used to finally determine the sensor design. To search for appropriate patterns, a numerical calculation is carried out over wide ranges of pitches and rotation angles. It is necessary to find an appropriate sensor pattern that minimizes the Moiré pattern, while maintaining the signal sensitivity. The interference between periodic display pixel arrays and sensor patterns can lead to the Moiré phenomenon. Even at this high transmittance, the electrodes can degrade the display quality when they are placed on the display. and a transmittance of ~94% (~86% with the substrate effect) in the visible wavelength range, and assembled onto a display panel. On-screen fingerprint sensors are fabricated using an indium tin oxide transparent conductor with a sheet resistance of ~10 Ω/sq. Applying the Drop Shadow effect to the shape wouldn't' do much, as the opacity is so low already, it won't show up to any useful degree.Īnd if you wanted to reuse this over and over in that particular production, but don't have Motion, Select the title clip and generator clip, make them a Compound Clip.In this study, a mutual capacitive-type on-screen fingerprint sensor, which can recognize fingerprints on a display screen to provide smartphones with full-screen displays with a minimal bezel area, is fabricated. But for a more subtle, softer look, leave the Drop Shadow turned off. Although enabling the Drop Shadow on the text would help, and I personally prefer it in this situation. I'd be cautions about what clips you use this on, as it is pure white, and if you place it on a light clip, it may not show up very well. Use the Basic title template, try out Ariel Hebrew as a starting place with your font, and set it up to look like you wish. Then move it down to the lower left of the frame as you wish. In the Inspector, Transform section, set Scale X to 70%, Scale Y to 25% (just starting points, tweak as desired), and set Opacity to 15%. ![]() In the Generators, in the Solids group, use the Whites generator, set to Ivory. It could be done in FCPX alone, but not saved as a template, but could be saved as a Compound Clip. Would be very easy to do in Motion as a title template.
