Referring to fig. 1 and 2, in a preferred embodiment, a schematic structural diagram of a screen assembly 100 of an intelligent terminal 200 is shown. The screen assembly 100 of the intelligent terminal 200 includes a display module 110, a screen cover 120, a sensor set and a support housing 140. The user observes the positive direction of the intelligent terminal 200 when holding the intelligent terminal 200, the screen cover 120 is arranged from top to bottom in advance to serve as an element for protecting the display module 110, the display module 110 is attached to the lower portion of the screen cover 120, the size of the display module 110 is basically equal to or smaller than that of the screen cover 120, and the portion, which is not attached with the display module 110, of the lower portion of the screen cover 120 is generally a frame body of the display module 110. In the below of display module assembly 110, be equipped with the support casing 140 as the center of intelligent terminal 200, support casing 140 supports screen cover 120 and display module assembly 110 to fixed above-mentioned position between them. A sensor set is attached and fixed under the display module 110, and in this embodiment, the sensor set includes at least two pressure sensors 130, and the pressure sensors 130 are attached under the screen cover 120 having the display module 110 in the projection direction, so that when the supporting housing 140 contacts and supports the side of the screen cover 120, the pressure sensors 130 do not contact the supporting housing 140 due to the separation between the pressure sensors 130 and the supporting housing 140. Simultaneously when the user pressed screen apron 120, the power of pressing made screen apron 120 take place deformation (can understand, the central point of deformation puts in the position of pressing to drive peripheral position deformation in the lump), along with the transmissibility of power, display module assembly 110 deformed thereupon, then drives pressure sensor 130 deformation in the lump. Due to the separation of the pressure sensor 130 from the support housing 140, the pressure sensor 130 moves along with the direction of the pressing force, i.e. towards the support housing 140, during the deformation process, and the deformation of the pressure sensor 130 will also change during the change of the magnitude of the pressing force. Considering that the pressure sensor 130 mainly determines the magnitude of the pressing force through the deformation amount, the deformation of the pressure sensor 130 should be achieved only by the pressing force, for which there is a displacement gap 150 between the support housing 140 and the pressure sensor 130, and during the deformation of the pressure sensor 130, the deformation (or the movement at a partial position) of the pressure sensor 130 is confined in the displacement gap 150 and is spaced apart from the support housing 140.
In various embodiments, the number and location of the pressure sensors 130 are not limited, and the types of the pressure sensors 130 include, but are not limited to, MEMS, resistive, capacitive, and the like. Meanwhile, the displacement gap 150 is arranged, so that when pressure is transmitted, deformation of the screen cover 120, the display module 110 and the pressure sensor 130 is not interfered by other structures, and a pressure value received by the pressure sensor 130 is accurate.
In a preferred embodiment, the pressure sensors 130 are symmetrically disposed along the length direction or the width direction of the display module 110, and the pressure sensors 130 are parallel to the side edges of the length direction or the width direction of the display module 110. That is, the display module 110 is divided into two parts along the middle of the length direction or the width direction, the number of the pressure sensors 130 is two, and the pressure sensors are respectively distributed on the upper part, the lower part or the left part and the right part of the display module 110, and can be arranged in axial symmetry no matter the upper part, the lower part or the left part and the right part, so that the upper part, the lower part or the left part and the right part can identify the pressing force equally when receiving the pressure.
Further, in this embodiment, the number of the pressure sensors 130 is 4, and the pressure sensors 130 are symmetrically arranged along the width direction of the display module, that is, 2 pressure sensors 130 are arranged at the back of the upper half of the display module, and 2 pressure sensors 130 are arranged at the back of the lower half of the display module, and each of the 2 pressure sensors 130 of the upper and lower parts is arranged at the trisection of the width direction, that is, the pressure sensors 130 of the upper and lower parts divide each half into 3 substantially identical regions, and the distances from the pressure sensors 130 to the edge of the display module and the middle of the display module are substantially the same, so that the pressure sensors 130 are substantially located at the middle of the upper and lower parts of the display module to uniformly receive the pressing force wherever the pressing force is applied.
Preferably or optionally, the screen assembly 100 further includes an adhesive-backed element 160 adhered between the pressure sensor 130 and the display module 110, so that the pressure sensor 130 and the display module 110 deform synchronously, that is, the pressure sensor 130 is adhered behind the display module 110 through the thin adhesive-backed element 160, and the adhesive-backed element 160 will not affect or absorb the deformation of the display module 110, so that the deformation of the display module 110 is substantially the same as that of the pressure sensor 130.
Further, after the screen cover 120 and the display module 110 receive the pressing operation, the screen cover 120 and the display module 110 deform concavely towards the supporting shell 140, although the screen cover 120 and the display module 110 are solid, no matter how large the pressing force is, the screen cover 120 and the display module 110 can generate a trace amount of deformation, and then the pressure sensor 130 is driven to deform concavely towards the supporting shell 140, and the deformation may not be recognized by naked eyes, but exists all the time. After the pressure sensor 130 identifies the deformation amount, an electrical signal is generated according to different deformation amounts, the electrical signal bears the magnitude of the pressing force, and then the pressure sensor 130 is electrically connected with a processing chip in the intelligent terminal 200 to send an electrical signal to the processing chip for further processing by the processing chip. It can be understood that most of the positions below the display module do not have the pressure sensor 130, therefore, a pressure sensing algorithm may be provided in the pressure sensor 130, and through the relationship between the deformation amount determined in the test environment, the corresponding relationship of the pressure sensor 130, and the pressure value, under the actual use obtained by looking up the table, the pressing force position and the pressing force size corresponding to the actual deformation amount of the pressure sensor 130 should be obtained, so that the electrical signal includes the above information for further processing by the processing chip.
In the above embodiment, the pressure sensor 130 includes the pressing sheet that generates the electric signal including the signal intensity based on the deformation amount of the deformation of the depression, thereby realizing that the pressure sensor 130 can recognize the magnitude of the pressure based on the deformation amount.
It is understood that the screen cover 120 has a deformation threshold, which can be determined by the material of the screen cover 120 itself, and the design of the supporting housing 140 should be designed such that the displacement gap 150 between the screen cover and the pressure sensor 130 is greater than the deformation threshold, so as to ensure that the pressure sensor 130 does not contact the supporting housing 140 under any pressing force, and no interaction force exists between the two.
The screen assembly 100 having the above-mentioned embodiment can be applied to the smart terminal 200, and the smart terminal 200 includes a housing that covers the processor on the internal motherboard and the screen assembly 100, and the surface of the housing is exposed to the screen cover 120, so that the user can view the display screen through the screen cover 120, and the portion without the display function is the frame of the screen cover 120.
The smart terminal may be implemented in various forms. For example, the terminal described in the present invention may include an intelligent terminal such as a mobile phone, a smart phone, a notebook computer, a PDA (personal digital assistant), a PAD (tablet computer), a PMP (portable multimedia player), a navigation device, and the like, and a fixed terminal such as a digital TV, a desktop computer, and the like. In the following, it is assumed that the terminal is a smart terminal. However, it will be understood by those skilled in the art that the configuration according to the embodiment of the present invention can be applied to a fixed type terminal, in addition to elements particularly for moving purposes.
It should be noted that the embodiments of the present invention have better practicability and are not intended to limit the present invention in any way, and any person skilled in the art may change or modify the technical contents disclosed above to equivalent effective embodiments, but all the modifications or equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention still fall within the scope of the technical solution of the present invention.
