Description

technical field [0001] The invention relates to a display screen, in particular to a display screen with a key function which saves the key area by making the display screen into a key structure. Background technique [0002] Many products have a display screen and a control button. Since the entire product is embedded in a large product, only one side of the entire product can be observed and touched by the user. Such products are often very small. If the LCD screen and control buttons are arranged on a surface that can be observed and touched by the user, it is easy to cause two results: one is that the display LCD is made very small, which affects the customer's information reading ; The second is that the control buttons are very small, which is very inconvenient for customers when controlling. [0003] For example, there are usually two or three extended button positions reserved on the front dashboard of a car, which are reserved for customers to place buttons when ad...

AI Technical Summary

Problems solved by technology

Such products are often very small. If the LCD screen and control buttons are arranged on a surface that can be observed and touched by the user, it is easy to cause two results: one is that the display LCD is made very small, which affects the customer's information reading ; Second, the control buttons are made very small, which is very inconvenient for customers to control

[0003] For example, there are usually two or three extended button positions reserved on the front dashboard of a car, which are reserved for customers to place buttons when adding functions to the car. The button area here is usually more than 30 millimeters by more than 20 millimeters, usually Under normal circumstances, this place is only used to place buttons to control the extended functions; it is also possible to use this location to place a display screen to display information related to the status of the car, but in this way, the buttons used for display control will be made small and unmanageable

[0004] To overcome this problem, many products can only use touch screens, but this solution greatly increases the cost of the product
