Description

Technical Field

[0001] The utility model relates to the technical field of display devices, and more specifically, to an OLED display screen with a vibration feedback function. Background Art

[0002] Large screens are the development trend of in-vehicle displays. More and more in-vehicle display screens are larger than 10 inches. However, as the screen size increases, its weight and volume will also increase, which is not conducive to lightweighting of the car. Traditional LCD screens are relatively thick, with more layers, including backlight modules, which make LCD screens thicker and heavier. Compared with LCD screens, OLED screens are thin and light, self-luminous, do not require backlight, have better contrast and color gamut, lower power consumption, and shorter response time. OLED screens are increasingly widely used.

[0003] OLED display screens with vibration feedback function are generally divided into a vibrator part and a stator part. The stator part is always fixed on the vehicle body and does not vibrate with the vibration of the vibration part. For example, Chinese patent CN220933469U discloses a touch display screen with vibration feedback function. By using a spring sheet arranged between the display touch module and the fixed component, when the vibration actuator generates vibration feedback, it can only drive the display touch module to vibrate, and the fixed component cannot vibrate accordingly, thereby protecting the safety of the PCBA board located on the rear shell and improving the overall vibration safety of the device. However, in the above scheme, the elastic sheet is used to connect the vibrator part and the stator part. Although it can improve the overall safety of the device, the role of the elastic sheet is to achieve shock absorption of the stator part structure, and the vibrator part is not provided with a corresponding structure to achieve shock absorption and buffering during vibration. In this way, on the one hand, long-term vibration will affect the connection stability of the vibrator part relative to the stator part, and on the other hand, a smooth and gentle touch cannot be obtained, which affects the user's experience.
