Problems solved by technology
The typical size of a single ultrasonic transducer is 1cm 2 , and each ultrasonic transducer is controlled independently, which makes the driving circuit particularly large and difficult to integrate with the display
Existing tactile feedback devices either use projection displays or place ultrasonic devices on the back of the display to project downwards, and have not truly integrated with the display

The present application discloses an ultrasonic tactile display device, a manufacturing method, and a display system. The display device includes a TFT layer, and the TFT layer includes a plurality of ultrasonic-driven TFTs. A pixel division layer is arranged above the TFT layer, and the pixel division layer There are a plurality of ultrasonic sensors, and each ultrasonic sensor corresponds to one ultrasonic driving TFT. According to the technical solution provided by the embodiment of the application, by fabricating a capacitive micro-machined ultrasonic sensor and its driving circuit on the OLED backplane of the display device, the ultrasonic tactile feedback device is integrated with the display device, which greatly reduces the size of the sensor and the driving circuit , by making an ultrasonic sensor with the number of pixels on the display device, the adjustable range of the tactile feedback force and the tactile experience are greatly improved at the same time.
Description
technical field [0001] The present disclosure generally relates to a display device, and in particular to an ultrasonic tactile feedback display device, a manufacturing method and a display system. Background technique [0002] As the latest computer input device, touch screen is currently the simplest, most convenient and natural way of human-computer interaction. It endows multimedia with a new look and is an attractive new multimedia interactive device. Although the touch screen of a smart device has brought many new experiences to users, it is convenient and fast, but people also lose the experience of pressing a physical keyboard. At the same time, people's demand for touch experience is also very strong. For example, when you touch the screen, you can feel the experience of touching a real object; when you play the Angry Birds game on the touch screen, you can feel the elasticity of the rubber band when you stretch the slingshot, and so on. [0003] The emergence of ...
