According to foreign media reports, one of the biggest problems for the future iPhone is whether Apple will insist on using face ID or touch ID with insufficient display. Apple continues to work on two forms of biometric security, and today patented a fingerprint sensor method that can be embedded in a display. The patent itself is a method of optically reading fingerprints. Existing iPhones with touch ID sensors use capacitive touch to read fingerprint settings, while Apple’s touch ID sensors on the 13 and 15 inch macbook pro and the new MacBook Air use the same technology.
Apple’s report clearly states that Apple uses an optical reader in its 16 inch MacBook Pro. Although it can be simply embedded in the power switch in the same way as the earlier capacitor versions, the optical reader can also be used to display insufficient touch IDs.
As will be understood by those skilled in the art, if the display is in the form of a touch display, the touch display can operate as both an input device and a display. In this way, the display will cooperate with the controller to perform one or more device functions in response to input. For example, device functions may include turning on or off power to an electronic device, initiating communication via a wireless transceiver, and / or performing menu functions based on input to a touch display.
The controller can change the display to display the menu of available applications based on pressing or input to the touch display. Of course, other device functions can be performed based on the input to the touch display. The portable housing may carry other or additional finger operated user input devices, such as a button switch, which may be alternatively or additionally used for device functions, as will be understood by those skilled in the art. The optical image sensor is carried by a housing under the display.
The optical image sensor senses biometric image data associated with the user, such as data of a biometric image representing a fingerprint pattern of the user’s finger. For example, the controller may perform the authentication function by matching the acquired biometric image data with the stored biometric template data stored in the memory. It will be understood by those skilled in the art based on the functions and / or performing the electronic controller. In some embodiments, there may be more than one optical image sensor.
There are various suggestions that Apple will replace the face ID with an underdisplayed touch ID or provide two forms of authentication.
Each form of biometric authentication has its advantages and disadvantages. Face ID is faster and can be authenticated immediately without explicit user operation. This is especially useful for applications such as banking applications, where you can log in seamlessly without doing anything. However, the sensor does need to leave some space on the front of the device, so as long as ordinary cameras and speakers can also be embedded in the display, the touch ID below the display can achieve a smaller border – or even no border at all.
In addition, both touch ID and face id have their own fans, so offering both options may be considered the best of both worlds, although that’s a less similar approach to Apple: the company usually thinks users don’t know what they want until you give it to them.
