[0022] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0023] Refer to the accompanying drawings, which is a device for improving the touch effect of a touch device implemented by the present invention. As shown in the figure, the device includes a touch screen 1, a pressure sensor film 3, a middle board 5 and a back cover 7, and a touch screen 1 A pressure sensor film layer 3 is fixed on the back side by an adhesive layer 2; an intermediate plate 5 is provided on the back of the pressure sensor film layer 3, wherein there is an appropriate safety gap 4 between the pressure sensor film layer 3 and the intermediate plate 5, the safety gap 4 is used to strain the pressure, so that the pressure sensor film 3 can be fully deformed, so that the pressure sensor film 3 can accurately calculate the pressure generation position.
[0024] The middle plate 5 has a II-shaped structure to facilitate the packaging of the touch screen 1 and the pressure sensor film layer 3, and at the same time, a safety gap 4 can be formed, and the two ends of the middle plate 5 extend outward to form another Confined space-containing cavity 6.
[0025] At the same time, the back cover 7 is provided on the back of the middle board 5, and there is a accommodating cavity 6 between the middle board 5 and the back cover 7; the back cover 7 has an II-shaped structure, and its two sides are supported by the two ends of the middle board 5. To form a receiving cavity 6. The accommodating cavity 6 is used for accommodating the touch screen and the control chip used for pressure sensor film control, and the above-mentioned control chips are integrated on the PCB board.
[0026] In other implementation manners, the control chips are set according to actual needs, and the control chips are not necessarily integrated on the same pcb board. Similarly, the control chip does not limit the control chips to be in the cavity 6.
[0027] A battery can also be arranged in the accommodating cavity 6 to provide power for the control chip, control circuit, touch screen, and pressure sensor film on the PCB board.
[0028] The control chip includes a touch screen control chip and a pressure sensor film control chip to calculate the touch position and the pressure generation position.
[0029] Moreover, the PCB board is also provided with a main chip, the touch screen control chip and the pressure sensor film control chip are both connected to the main chip, the specific position of the touch is obtained through the main chip, and control instructions are accepted to perform corresponding control operations.
[0030] The method for improving the touch effect of a touch device implemented by the present invention adopts a touch screen and a pressure module to work at the same time. The touch screen is used to detect the position information of the user's touch. The pressure module detects the pressure of the user's touch while providing the position information of the pressure. After the information, the location information of the touch and the location information generated by the pressure are reported to the system.
[0031] The pressure module is realized by the pressure sensor film layer and its control chip. The position information of the touch and the position information generated by the pressure are summarized and reported by the main chip. The touch screen transmits the position data of the touch to the touch screen control chip, and the position data generated by the pressure is transmitted from the pressure sensor film to the pressure sensor film. In the control chip, the touch screen control chip calculates the position information of the touch and the pressure sensor film control chip calculates the position information of the pressure, and transmits the position information of the touch and the position information of the pressure to the main chip for summary.
[0032] When the user's finger is in good contact with the touch screen system, the touch screen can obtain an accurate touch position. This touch position is consistent with the pressure generating position calculated by the pressure module. The main chip compares the touch position calculated by the touch screen with the pressure calculated by the pressure module. The position is reported to the system.
[0033] When the user's finger is not in good contact with the touch screen system ground, the touch position calculated by the touch screen control chip is inaccurate, or the touch position cannot be detected, but the pressure module can calculate the pressure generation position normally. At this time, the main chip summarizes If there is a discrepancy in the information, the main chip can notify the touch screen control chip of this result. After the touch screen control chip obtains this information, it can sample and reduce the touch threshold to recalculate the user's touch position.
[0034] If the correct touch position can be obtained after lowering the threshold, the main chip will continue to use the touch position calculated by the touch screen. If the touch screen still cannot obtain the correct touch position after lowering the threshold, the main chip will report the touch position calculated by the pressure module to system.
[0035] The device and method for improving the touch effect of touch equipment realized by the present invention has a pressure touch module. When a finger touches, the pressure touch module can detect the pressure change, and at the same time can calculate the pressure generating position. When the touch screen is not in good contact with the system ground due to the finger, the pressure touch module is used to identify the touch position to improve the problem of inaccurate detection of the touch screen.
[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included in the protection of the present invention. Within range.
