Abstract
The present invention relates to display field, especially a kind of automatic detection touches method and the display unit of key-press status, it is characterized in that: providing a control chip to connect a touch modules, the touch in order to described touch modules to be sent is converted to signal to noise ratio and sensitivity by key signals; A display module is provided to connect described control chip, in order to show described signal to noise ratio and sensitivity. Touch is converted into sensitivity and signal to noise ratio by the present invention by key signals, is shown to the factory menu of display unit by controlling the OSD display chip of chip, enables operator read the data of button intuitively by factory menu like this.
Description
Technical field
The present invention relates to display field, especially a kind of automatic detection touches method and the display unit of key-press status.
Background technology
Touch keypress function is more and more to be used in various display equipment, replaces the button of coventional type gradually, and touch-type keystroke sensitivity parameter setting and verification step are very complicated, and not accurate. In the prior art, need during test to remove touch key-press module, it is external to measurement jig, again measurement jig is received on PC, then being read the trigger value of key value and software design by PC, be used for judging button design value whether in the pre-degree of design, this kind of method operation is too complicated, and cannot in complete machine read value, there is bigger quality hidden danger.
Also do not have in the prior art a kind of easily, efficiently, accurately, read the method for touch controlled key sensitivity and signal to noise ratio intuitively, the hidden danger of degradation in efficiency and quality to be caused; There is following shortcoming in prior art:
1. touch the button design stage cannot intuitive judgment button design value whether in the pre-degree of design;
2. the experiment of trust property relies on manual operation to judge, there is the risk that cannot predict;
3. touching during key type display equipment is produced the process capability that cannot obtain touch button;
4. cannot judge bad module during terminal market after sale service, cannot convenient keep in repair.
Summary of the invention
In view of this, it is an object of the invention to provide method and display unit that a kind of automatic detection touches key-press status.
The present invention adopts following scheme to realize: a kind of automatic detection touches the method for key-press status, it is characterised in that: providing a control chip to connect a touch modules, the touch in order to described touch modules to be sent is converted to signal to noise ratio and sensitivity by key signals; A display module is provided to connect described control chip, in order to show described signal to noise ratio and sensitivity.
In an embodiment of the present invention, described touch modules is by I2C agreement and described control chip communication.
In an embodiment of the present invention, described touch button signal comprise described touch modules by the maximum value of key signals and noise figure.
In an embodiment of the present invention, described signal to noise ratio equals described maximum value and the ratio of described noise figure, and described sensitivity equals described maximum value and the ratio of a preset trigger.
The present invention also provides a kind of automatic detection to touch the display unit of key-press status, it is characterised in that, comprising:
One touch modules;
One control chip, is connected with described touch modules, and the touch sended in order to receive described touch modules by key signals and is converted to signal to noise ratio and sensitivity; And
One display module, is connected with described control chip, in order to show described signal to noise ratio and sensitivity.
In an embodiment of the present invention, described control chip also comprises an OSD display chip and connects described display module, is displayed in the OSD menu of described display unit in order to control described signal to noise ratio and sensitivity.
In an embodiment of the present invention, also comprise a power supply module, with thinking that described display unit is powered.
In an embodiment of the present invention, described touch modules is by I2C agreement and described control chip communication.
In an embodiment of the present invention, described touch button signal comprise described touch modules by the maximum value of key signals and noise figure.
In an embodiment of the present invention, described signal to noise ratio equals described maximum value and the ratio of described noise figure, and described sensitivity equals described maximum value and the ratio of a preset trigger.
The present invention is by carrying out technological innovation to existing indicating meter, touch key value is converted into sensitivity and signal to noise ratio, the factory menu being shown to display unit by the OSD display chip of control chip (ScalerIC), enables operator read the data of button intuitively by factory menu like this; Development in the early stage, it is also possible to do criterion design review easily via factory menu, avoids the risk that manual operation is judged and read by the measurement jig of outside, simultaneously raising efficiency; Simultaneously, it is possible to improve the process capability that band touches the display unit of button and produces, promote the market quality touching button, and market is safeguarded easily.
