Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 is a schematic structural diagram of a rear cover touch structure of a smart phone according to a preferred embodiment of the present invention; fig. 2 is a schematic structural diagram of a self-contained touch ITO routing layer 202 of a rear cover touch structure of a smart phone according to the present invention; fig. 3 is a schematic structural diagram of a back cover touch structure mutual capacitance type touch ITO routing layer 202 of the smart phone in the present invention.
As shown in fig. 1 to 3, the rear cover touch structure of a smart phone provided by the present invention includes: lid 101, light guide plate 102, touch-control lamp light layer 103 and PCB board 104 behind the cell-phone that sets gradually, touch-control lamp light layer 103 includes: the touch ITO routing layer 202 and the plurality of LED lamps 105, wherein the touch ITO routing layer and the LED lamps 105 are both electrically connected to the PCB board 104, and the touch ITO routing layer 202 is configured to receive a touch instruction and send the received touch instruction to the PCB board 104; the PCB board 104 is configured to receive a touch instruction sent by the touch ITO routing layer 202, and control the LED lamp 105 according to the received touch instruction.
That is to say, the LED lamp 105 of the smart phone provided with the rear cover touch structure is controlled as follows: a user touches the rear cover 101 of the mobile phone, the touch ITO routing layer 202 detects a touch position, a touch manner, and the like, and sends the obtained information to the PCB 104, and the PCB 104 converts the obtained information into a corresponding control instruction to control the corresponding one or more LED lamps 105 to complete corresponding actions, such as turning on, turning off, or brightness.
Meanwhile, the invention also considers the following problems: firstly, burrs exist on the surface of the rear cover 101 of the mobile phone, and when an ITO Film (indium tin oxide conductive Film) is attached to the rear cover 101 of the mobile phone, ITO wiring is easily scratched, and the production yield is reduced; second, when the mobile phone rear cover 101 is designed to be non-planar, the ITO wiring is easily broken during the attaching process due to the poor bending resistance of the ITO. In order to solve the above problem, the invention adopts the method of providing the copper leakage area 204 on the PCB 104 and manufacturing Touch Pattern (i.e. Touch ITO trace layer 202) through copper leakage, so that the rear cover 101 of the mobile phone has a Touch function, as shown in fig. 2 and 3.
In the prior art, the reason that the light effect of the mobile phone rear cover 101 is controlled through the display screen is that the mobile phone rear cover 101 does not have a touch function and cannot complete touch control. The invention completes the task with low cost and high effect by touching the ITO routing layer 202.
The touch ITO trace layer 202 is disposed on the first layer of the PCB 104 in order to ensure that the touch ITO trace layer 202 can sense touch information accurately and sensitively even under a long-distance operation of a touch finger, and has sufficient touch sensing variation and anti-interference capability.
In a further preferred embodiment, the PCB board 104 is specifically configured to: receiving a touch instruction sent by the touch ITO trace layer 202, calculating a touch coordinate according to the received touch instruction, and controlling the LED lamp 105 located within the touch coordinate setting range according to the calculated touch coordinate. That is, the control of the LED lamp 105 is achieved by division or according to a predetermined rule (which is set around coordinates).
Specifically, Touch Pattern is a setting mode of the Touch ITO routing layer 202, and the present invention provides a self-capacitance type and a mutual capacitance type, which are respectively described below.
As shown in fig. 2, the self-contained type means that the receiving and sending of the touch ITO trace layer 202 are integrated, and through the above description, the function of the touch ITO trace layer 202 has been clarified, and is divided into two parts, namely, receiving a touch instruction generated by a user touching the rear cover 101 of the mobile phone, and sending the received touch instruction to the PCB 104 according to a specific format (the format is not specifically limited); self-contained is where both functions are performed by the same component.
In a specific implementation, at least 9 rows, three rows and three columns are arranged in the row of the copper leakage area 204; each copper leakage area 204 is square, and four LED lamps 105 are arranged in rows and columns in the inner part. Corresponding to the copper leakage area 204, the touch ITO routing layer 202 is divided into a plurality of touch ITO routing layer blocks, the portion outside the LED lamp 105 is the touch ITO routing layer block, and the LED lamp 105 and the touch ITO routing layer block in the copper leakage area 204 form a corresponding touch light area.
It should be noted that the specific configuration is only one embodiment of the present invention, and is used to illustrate the technical solution in detail, and may be appropriately adjusted when the specific configuration is used, so that this portion cannot be used to limit the protection scope of the present invention.
As shown in fig. 3, it can be understood that mutually-compatible receiving and sending functions are performed by two different components, namely, a touch command receiving bar 301 and a touch command sending bar 302, in order to set rules applicable to each position of the mobile phone rear cover 101, the present invention sets a plurality of touch command receiving bars 301, and sets a plurality of touch command receiving bars 301 in parallel and at intervals, and sets a touch command sending bar 302 in the same way. In order to make the response speed and the like of the receiving and sending in various places the same, the invention also provides a touch instruction receiving bar 301 perpendicular to the touch instruction sending bar 302.
In order to make the arrangement of the LED lamp 105 regular and orderly, the touch lamp light layer 103 of the present invention further includes: the LED lamp 105 accommodating area is formed by encircling two adjacent touch instruction receiving strips 301 and two adjacent touch instruction sending strips 302.
Because the touch instruction receiving bar 301 receives a touch instruction generated by the touch of a user and the touch instruction sending bar 302 sends the instruction to the PCB 104, the invention arranges the touch instruction receiving bar 301 on the upper layer and the touch instruction sending bar 302 on the lower layer, on one hand, the distance between the touch instruction receiving bar 301 and the mobile phone rear cover 101 is reduced, on the other hand, the touch instruction sending bar 302 is directly contacted with the PCB 104, thereby avoiding wiring and other connections and simultaneously improving the response speed of the touch instruction. In order to facilitate routing and appearance aesthetics, Touch ICs (i.e., Touch ICs) are directly SMT on the same layer as Touch patterns. SMT refers to a surface mounting technology, and in the invention, refers to a technology for mounting devices on a mobile phone mainboard.
The invention also provides a mobile phone which comprises the rear cover touch structure of the smart phone.
It is to be understood that the invention is not limited to the examples described above, but that modifications and variations may be effected thereto by those of ordinary skill in the art in light of the foregoing description, and that all such modifications and variations are intended to be within the scope of the invention as defined by the appended claims.
