Embodiment
For above-mentioned feature and advantage of the present invention can be become apparent, the embodiment that exemplifies cited below particularly, and cooperate institute's accompanying drawing to elaborate.
Fig. 1 is the device schematic diagram of the screen crush protector of invention one embodiment.Please refer to Fig. 1, screen crush protector 10 devices are on an electronic installation (not illustrating), and screen crush protector 10 comprises screen 100, extruding sensing module 110, output unit 120 and processor 130.In the present embodiment, screen 100 can be the frivolous display device of any panel, such as liquid crystal display that possesses touch controllable function (Liquid Crystal Display) etc., is not limited to above-mentioned.Extruding sensing module 110 is arranged at the below of screen 100, the pressure that bears in order to detect screen 100, and according to this Output pressure pressure signal.It is worth mentioning that, extruding sensing module 110 is not limited to be arranged at the ad-hoc location of screen 100 belows, only needs for can successfully detecting the position of screen 100 pressure that bears.In the present embodiment, a better setting position is screen 100 Centromedian belows, but that the present invention is not limited to is above-mentioned.
Fig. 2 is the device schematic diagram of the screen crush protector of one embodiment of the invention.Embodiment illustrated in fig. 2 can be with reference to the explanation of Fig. 1, wherein Fig. 2 is that embodiment provides the extruding sensing module 110 1 kinds of comparatively detailed operations.Please refer to Fig. 2, extruding sensing module 110 comprises pressure-sensitive resistance unit 111, voltage amplification unit 112 and comparing unit 113.The pressure that pressure-sensitive resistance unit 111 bears in order to detect screen, and Output pressure the first pressure voltage VP1 that bears according to screen.Voltage amplification unit 112 is connected to pressure-sensitive resistance unit 111, and receives the first pressure voltage VP1 from pressure-sensitive resistance unit 111, and amplifies the first pressure voltage VP1 and become the second pressure voltage VP2.
Comparing unit 113 is connected to voltage amplification unit 112, and 112 receive the second pressure voltage VP2 from the voltage amplification unit, and compares the second pressure voltage VP2 and preset reference voltage VREF.Preset reference voltage VREF sets according to the pressure preset upper limit value that screen can bear.And as the second pressure voltage VP2 during greater than preset reference voltage VREF, represent that the pressure that present screen bears has surpassed default higher limit, comparing unit 113 with output pressure signal SP to processor 130.
It should be noted that, because the first pressure voltage VP1 that conversion provides according to pressure is often too faint for pressure-sensitive resistance unit 111, can't reach the working range of comparing unit 113, therefore need voltage amplification unit 112 that the first pressure voltage amplification is become the second pressure voltage VP2 so that compare in the remittance comparing unit 113.If but in actual conditions, pressure-sensitive resistance unit 111 can directly be provided at the pressure voltage in comparing unit 113 working ranges, or use have good accuracy, comparing unit 113 that working range is large, that is to say, comparing unit 113 can directly receive the first pressure voltage VP1 to be judged, then (removing) optionally do not implemented in voltage amplification unit 112.At this moment, preset reference voltage VREF must re-start setting by corresponding such embodiment.
Fig. 3 is the embodiment schematic diagram of the pressure-sensitive resistance unit of one embodiment of the invention.Please refer to Fig. 3, pressure-sensitive resistance unit 111 comprises resistance R 1, R2, R3 and R4, is connected to each other in the mode of Gordon Adams Bridge (Wheatstone Bridge).The first end of resistance R 1 and R3 couples supply voltage VCC, and the second end of resistance R 1 and R3 then couples respectively the first output terminal OUT1 and the second output terminal OUT2 of pressure-sensitive resistance 111.The first end of resistance R 2 and R4 couples reference voltage REF2, the second end of resistance R 2 and R4 then couples respectively the first output terminal Out1 and the second output terminal Out2 of pressure-sensitive resistance 111, wherein reference voltage REF2 can be a negative voltage or a ground voltage, actual conditions when implementing and setting, the present invention is not limited to above-mentioned.
In the present embodiment, resistance R 1 is a force-sensing resistor, is used for the pressure that detecting screen (such as the screen 100 of Fig. 1) bears.When force-sensing resistor R1 is under pressure extruding, then will adjust according to the size of this pressure the resistance value of force-sensing resistor R1.In the situation that is not subject to any pressure extrusion, resistance R 1 is identical with the impedanoe ratio of resistance R 4 with impedanoe ratio and the resistance R 3 of resistance R 2, and output terminal Out1 and Out2 do not export any voltage or electric current.And when force-sensing resistor R1 receives pressure, therefore the resistive impedance value of force-sensing resistor R1 changes, cause resistance R 1 no longer identical with the impedanoe ratio of resistance R 4 with ratio and the resistance R 3 of resistance R 2, the potential difference (PD) of output terminal Out1 and Out2 is the first pressure voltage VP1.
Fig. 4 is the flow chart of steps of the screen extruding guard method of one embodiment of the invention.Please refer to Fig. 4, at first, when step S401, the pressure that bears of detecting screen, when pressure during greater than preset upper limit value, the output pressure signal.Then, when step S402, receive pressure signal after, the transfer control signal to output unit with output warning notice.
Fig. 5 is the flow chart of steps of the screen extruding guard method of one embodiment of the invention, compared to embodiment illustrated in fig. 4, embodiment illustrated in fig. 5ly provides comparatively detailed implementation step.Please be simultaneously with reference to Fig. 2 and Fig. 5, at first, when step S501, pressure-sensitive resistance unit 111 is detected the pressure that screens bear, and according to Output pressure the first pressure voltage VP1.Then, when step S502, voltage amplification unit 112 receives the first pressure voltage VP1 from pressure-sensitive resistance unit 111, and amplifies the first pressure voltage VP1 and obtain the second pressure voltage VP2.
Then, when step S503, comparing unit 113 receives the second pressure voltage VP2 and compares with preset reference voltage VREF.If the second pressure voltage VP2 is not greater than preset reference voltage VREF, the pressure that expression screen 100 bears not yet surpasses the preset upper limit value of the pressure that can bear, and then gets back to step S501 and continues the pressure that detecting screen 100 bears.If the second pressure voltage VP2 is greater than preset reference voltage VREF, the pressure that expression screen 100 bears has surpassed preset upper limit value, and then comparing unit 113 output pressure signal SP are to processor 130 (step S504).When step S504, processor 130 is after receiving pressure signal SP unceasingly, and transfer control signal CNG is to output unit 120.After output unit 120 receives control signal CNG, then utilize aforesaid embodiment, modes such as the tinkle of bells, vibration, the output warning notice is to notify the user.
In sum, the present invention proposes a kind of screen crush protector and method thereof, when the pressure that bears when screen has surpassed the maximal value that can bear, notifies the user with the prompting effect, so that the user can avoid causing the damage of screen in automatic situation.
Although the present invention with embodiment openly as above; so it is not to limit the present invention; any the technical staff in the technical field; without departing from the spirit and scope of the present invention; when can doing a little equivalents and modification, therefore protection scope of the present invention defines and is as the criterion when looking the appended claim book.
