The invention can realize compatibility of touch screens with/without the ICON without affecting the functions of display and operation function or quality, thereby saving the design and production cost.
Description
Technical field
The present invention relates to LCM touch-screen field, particularly a kind ofly realize LCM touch-screen compatible band ICON and not with the method for ICON.
Background technology
At present, the band ICON that LCM (Liquid Crystal Module) touch-screen has (small icon of the touch-screen of LCM below), what have is not with ICON, so just need carry out different designs, to cooperate band ICON and not with the different operating demand of the touch-screen of ICON.But, under all identical situation of other software and hardware conditions, only, will divide other design owing to whether be with ICON, increased the input and the production cost of design.If can be under the prerequisite that does not influence Presentation Function and quality, realize band ICON and not with the compatibility of the touch-screen of ICON, greatly the input of save design and production cost.
Summary of the invention
The object of the present invention is to provide a kind of LCM of realization touch-screen compatible band ICON and not with the method for ICON, under the prerequisite that does not influence demonstration and operating function and quality, can realize with ICON with not with the compatibility of the touch-screen of ICON, thereby can save cost greatly.
LCM touch-screen compatibility provided by the present invention is with ICON and not with the method for ICON, is may further comprise the steps:
(1) according to whether being with ICON, for LCM sets different ID number;
(2) respectively the LCM touch-screen is carried out different initialization according to ID number the difference of LCM, wherein, the initialization of the LCM touch-screen of band ICON comprises sets the function that its each ICON will carry out; The initialization with the LCM touch-screen of ICON is not included as the displayable maximum pixel point assignment of the LCM longitudinal axis;
(3) the touch message received of LCM touch-screen is through ADC (analog-converted becomes numeral) conversion imaging vegetarian refreshments;
(4) carrying out different pixels respectively according to ID number the difference of LCM handles, wherein, not with the longitudinal axis maximum constraints of the pixel of the LCM touch-screen of ICON on the maximum effective pixel points of the longitudinal axis of LCM touch-screen, promptly partly all be not made as the maximum pixel point of the LCM longitudinal axis at the longitudinal axis maximum pixel point that exceeds LCM with the LCM pixel of ICON; The LCM pixel of band ICON is constant;
(5) since band ICON with the pixel with the LCM of ICON is not different, make band ICON and can Be Controlled execution different operating with the LCM of ICON, wherein, when touching this and not exceeding LCM longitudinal axis maximum pixel point part with the LCM touch-screen of ICON, what carry out is the function of LCM longitudinal axis maximum pixel point, and can not carry out the function of ICON, and the LCM of band ICON does not then add restriction, when the some ICON on this touch-screen of touch, will carry out the pairing function of this ICON.
Wherein, the value of the displayable maximum pixel point of the described LCM longitudinal axis is after described LCM touch-screen is removed the ICON part, the value of the longitudinal axis at the maximum region place that can show.
Further, described step (2) also comprises the hardware and software initialization to the LCM touch-screen.
Further, the touch message that the touch-screen of described step (3) LCM is received is meant that through ADC conversion imaging vegetarian refreshments the LCM touch-screen transverse axis and the longitudinal axis read ADC value several times respectively, and the linear dependence according to itself and pixel obtains its pixel.
About detailed content of the present invention, will do further the present invention with specific embodiment in conjunction with the accompanying drawings and set forth.
Description of drawings
Fig. 1 is LCM touch-screen compatible band ICON and is not with ICON functional method implementation structure figure.
Fig. 2 is that the LCM touch-screen is received and touched ADC sampling process flow diagram after the message.
Fig. 3 is band ICON and the process flow diagram that is not converted to pixel with the LCM touch-screen of ICON through ADC;
Embodiment
The present invention is further described below in conjunction with drawings and Examples.
As shown in Figure 1, a kind ofly realize LCM touch-screen compatible band ICON and, may further comprise the steps not with the method for ICON:
(1) according to whether being with ICON, for LCM sets different ID number;
(2) respectively the LCM touch-screen is carried out different initialization according to ID number the difference of LCM, wherein, the initialization of the LCM touch-screen of band ICON comprises sets the function that its each ICON will carry out; The initialization with the LCM touch-screen of ICON is not included as the displayable maximum pixel point assignment of the LCM longitudinal axis;
(3) the touch message received of LCM touch-screen is through ADC (analog-converted becomes numeral) conversion imaging vegetarian refreshments;
(4) carrying out different pixels respectively according to ID number the difference of LCM handles.
Described step (2) also comprises the hardware initialization to the LCM touch-screen, wherein, and to the hardware initialization of LCM touch-screen, for baseband processing chip provides major clock and required power supply for the LCM touch-screen.
Described step (2) also comprises the software initialization to the LCM touch-screen, and it comprises LCM touch-screen initialization.
The message of receiving the LCM touch-screen in the described step (3) is meant with felt pen or finger etc. touch-screen is touched, produce and interrupt, ADC sampling is read in transmission, whether reaches predetermined hits according to the sampling ADC number of times of the transverse axis and the longitudinal axis and judges whether to stop to read the ADC sampling.Specifically as shown in Figure 2, may further comprise the steps:
A) after the LCM touch-screen interrupts arriving, send and read the ADC sampled signal, handle ADC and read sampling;
B) it is inferior to read touch-screen transverse axis ADC value N (N is predefined number of times) earlier, and record respectively;
C) if the N value is not less than the sampled value of default ADC, jump to d), otherwise jump to b);
D) read the touch-screen longitudinal axis ADC value N time, and record respectively;
E) if the N value is not less than the sampled value of default ADC, jump to f), otherwise jump to d);
F) calculate the transverse axis and the longitudinal axis value (getting its average) of reading ADC for N time respectively;
G) the ADC value of the transverse axis and the longitudinal axis is converted to the pixel of the transverse axis and the longitudinal axis;
Described step (4) as shown in Figure 3, carrying out different pixels respectively according to ID number the difference of LCM handles, wherein, not with the longitudinal axis maximum constraints of the pixel of the LCM touch-screen of ICON on the maximum effective pixel points of the longitudinal axis of LCM touch-screen, promptly partly all be not made as the maximum pixel point of the LCM longitudinal axis at the longitudinal axis maximum pixel point that exceeds LCM with the LCM pixel of ICON; The LCM pixel of band ICON is constant.
Because band ICON is with the pixel with the LCM of ICON is not different, make band ICON and can Be Controlled execution different operating with the LCM of ICON, wherein, when touching this and not exceeding LCM longitudinal axis maximum pixel point part with the LCM touch-screen of ICON, what carry out is the function of LCM longitudinal axis maximum pixel point, and can not carry out the function of ICON, and the LCM of band ICON does not then add restriction, when the some ICON on this touch-screen of touch, will carry out the pairing function of this ICON.
Being inventive embodiment only in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should be technology category of the present invention.
