A keyboard display module, display screen and mobile terminal

Abstract

The invention provides a keyboard display module, a display screen and a mobile terminal, the keyboard display module includes a display screen, the display screen includes a main screen area and a variable keyboard display area, and the variable keyboard display area includes a keycap , film domes and sensor layers. By eliminating the use of the existing FPC and metal pins in the embodiment of the present invention, the problem of shielding the touch sensor is avoided. At the same time, by setting the film pins above the sensor layer, the display screen will not be damaged when pressed. The deformation becomes larger, and the available pressing times are greatly increased without affecting the touch function, which improves the reliability of the module.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a keyboard display module, a display screen and a mobile terminal. Background technique [0002] With the development of smart phones, full screen has become a popular design and function of mobile phones. However, keyboard phones, as a classic style and irreplaceable button experience and input efficiency, have become an important branch of mobile phone product design. [0003] Nowadays, the full-screen design of smartphones is rapidly developing and popular. The keyboard area of ​​a full-keyboard phone will greatly reduce the display area and screen-to-body ratio of the front of the phone. The physical full keyboard occupies a large amount of surface area on the front of the phone, but it is only used as letters , numbers, character symbols and other input functions, the functionality is not enough to meet the expectations of mobile phone users who love full...

[0003] Nowadays, the full-screen design of smartphones is rapidly developing and popular. The keyboard area of ​​a full-keyboard phone will greatly reduce the display area and screen-to-body ratio of the front of the phone. The physical full keyboard occupies a large amount of surface area on the front of the phone, but it is only used as letters , numbers, character symbols, etc., the functionality is not enough to meet the expectations of mobile phone users who love full keyboards

[0004] In the traditional mobile phone keyboard design, a flexible printed circuit (FPC) or a metal dome is placed under the display screen for pressing. The deformation of the display screen will become larger when pressing, resulting in that the number of pressing times cannot meet the standards of consumer-grade products.

If the FPC or metal metal pin is placed above the display screen, a flexible circuit board is required to sense the switch status of the FPC or metal metal pin, and the metal pin needs to be made of metal. The conductive part of the circuit board is metal and opaque, and there will be a problem of shielding the sensor
