Apple has black technology: use the eyes to control the iPhone
In addition to the various functions that can be performed on the touch screen, some mobile phones have also added voice control and gesture control functions to enable users to perform some operations even without touching the mobile phone. As for the iPhone, a new operation may be introduced in the future, because in the latest patent document, it can be seen that Apple has designed a function that can be operated by eyes alone.
On the official website of the United States Patent and Trademark Office (USPTO), a new Apple patent was published. In the patent called "Delay of Display Event Based on User Gaze," Apple-designed devices such as the iPhone will be able to track the eye movements of the user and determine the line of sight. Where to stay on the screen, the system will respond to this and display the appropriate content at the point where the viewpoint stays.
For example, in the example of the patent document, it can be seen that in the past, when the user input text, the typo is erroneous, and the prompt box of the correct word will pop up on the screen immediately; however, under this new patent, you may have to look at it later. The typo will pop up, and the more important point is that you can even use your eyes to pick the correct words.
Of course, as Apple has applied for thousands of patents in the past, it does not mean that Apple will definitely use this eye-catching function. In addition, in fact, some manufacturers have launched similar eye tracking technology. For example, the Galaxy S4 launched by Samsung in 2013 can already detect the eyes of users, and can use this to tentatively play and drag the video. Move the page and so on. As for Apple, a graphical user interface patent obtained earlier this year can also be used to control a device by eye.
LCD (short for Liquid Crystal Display) liquid crystal display. The LCD structure is to place a liquid crystal cell between two parallel glass substrates. The lower substrate glass is equipped with TFT (Thin Film Transistor), and the upper substrate glass is equipped with a color filter. The liquid crystal molecules are controlled by the signal and voltage changes on the TFT. Rotate the direction, so as to control whether the polarized light of each pixel point is emitted or not to achieve the purpose of display. LCD has replaced CRT as the mainstream, and the price has dropped a lot, and it has become fully popular.
According to data from CINNO Research, 2020 is expected to be the first year for mass production of mobile phones with fingerprint recognition under LCD screens.
LCD features:
(1) Low-voltage micro power consumption
(2) The appearance is small and exquisite, the thickness is only 6.5~8mm
(3) Passive display type (no glare, no irritation to human eyes, and no eye fatigue)
(4) The amount of display information is large (because the pixels can be made small)
(5) Easy to colorize (reproduce very accurately on the chromatogram)
(6) No electromagnetic radiation (safe for the human body, conducive to information confidentiality)
(7) Long life (this kind of device has almost no deterioration problem, so the life is extremely long, but the life of the LCD backlight is limited, but the backlight part can be replaced)
