A kind of feature operation interface images combination display packing
Technical field
The invention belongs to the display technique field, relate in particular to the technology of the feature operation interface display of household electrical appliance.
Background technology
The display mode of household electrical appliance becomes increasingly complex, from initial common light emitting diode indication, to charactron video data and state etc., arriving vacuum fluorescent display screen again shows, segmentation liquid crystal display, lattice lcd show, the most high-end up till now TFT-LCD (Thin Film Transistor) Thin Film Transistor (TFT) liquid crystal display, wherein the TFT liquid crystal display can realize that the picture of true color shows, can be so that the human-computer interaction interface of household electrical appliance is more attractive in appearance.
When utilizing TFT-LCD, when system detects user's button operation or Data Update, need to upgrade picture in its entirety as the human-computer interaction interface of household electrical appliance.Design in the comparatively complicated system in function, need Showing Picture of renewal may reach the width of cloth up to a hundred.In cost sensitivity, household electric appliances with keen competition, need prestore width of cloth pictures up to a hundred before the product export in storer, increased the cost of domestic electric appliances controller greatly.
Summary of the invention
At in the above-mentioned domestic electric appliances controller in the existing deficiency of feature operation interface display technical elements, the invention provides a kind of combination display packing of feature operation interface display picture, this method can significantly reduce the quantity of combination picture, thereby reduce requirement to system storage capacity, significantly improve the refresh rate of picture, reduction is to the requirement of system running speed, thus the reduction cost of products.
Technical solution of the present invention is: a kind of feature operation interface images combination display packing may further comprise the steps:
1) in system memory space, prestore background picture and element picture;
2) main control chip sends the control command of combination picture, wherein includes the information of the picture width of cloth number that need be combined into, every width of cloth combination picture and the information of each element picture;
3) after the display module controller is received above-mentioned control command, carry out the picture combination, the first step shows initial picture according to the control command that obtains; Second step, when need upgrading picture, with intend upgrading picture background picture numbering and initial picture background picture relatively, if difference then shows the combination picture that a width of cloth is new,, then carry out next step if identical; The 3rd step, compare intending the pixel of renewal element picture and the finite element picture of same coordinate position, if identical, then directly cover the finite element picture with upgrading the element picture at this coordinate position; If different, then utilize clear screen command to remove the finite element picture, again at the element picture of this coordinate position display update.
The information of described combination picture comprises the needed background picture numbering of numbering, this picture of forming this picture and needs the number of element picture.
The information of described element picture comprises numbering, pixel, coordinate position and the check code of this element picture on background picture of elemental map sheet.
Above-mentioned display module controller is a Thin Film Transistor (TFT) liquid crystal display mode block controller.
Feature operation interface images of the present invention is combined by background picture and some element pictures, comes the processing capacity button to show by this element picture array mode, can significantly reduce the requirement of the quantity minimizing of combination picture to system memory size; In the time will showing the change of some or several elementary states, the demonstration that only needs to upgrade the respective element position gets final product, and required data updated is few, can significantly improve the refresh rate of picture, reduces the requirement to system running speed, thereby reduces cost.

Embodiment
The present invention is described further below in conjunction with the drawings and specific embodiments.
A kind of feature operation interface images combination display packing may further comprise the steps:
1) in system memory space, prestore background picture M and element picture N;
2) main control chip sends the control command of combination picture, wherein include the information of the picture width of cloth number that need be combined into, every width of cloth combination picture and the information of each element picture, the information of described combination picture comprises the needed background picture numbering of numbering, this picture of forming this picture and needs the number of element picture that the information of described element picture comprises numbering, pixel, coordinate position and the check code of this element picture on background picture of elemental map sheet;
3) after the display module controller is received above-mentioned control command, carry out the picture combination, as shown in Figure 1, the first step shows initial picture P0 according to the control command that obtains; Second step, when need upgrading picture, with intend upgrading picture P1 background picture M1 numbering and initial picture P0 background picture M0 relatively, if difference then shows the combination picture P1 that a width of cloth is new,, then carry out next step if identical; The 3rd step, compare intending the pixel of renewal element picture N1 and the finite element picture N0 of same coordinate position, if identical, then directly cover finite element picture NO with upgrading element picture N1 at this coordinate position; If different, then utilize clear screen command to remove finite element picture NO, again at this coordinate position display update element picture N1.
Feature operation interface with electromagnetic oven is an example, and shown in Fig. 2,3, but the feature operation interface is divided into key area and 1 M0 background area that K1~K10 amounts to 10 touch-controls.Each element picture correspondence is shown in the key area, and the background picture correspondence is shown in the background area.Be pre-stored with M width of cloth background picture and N width of cloth element picture in the electromagnetic oven system memory space.
As shown in Figure 4, start is defaulted as " Baoshang " function, shows initial picture P0.Initial picture P0 is made up of background picture M0 and 5 width of cloth element pictures (" Baoshang ", " regularly ", " reservation ", " intelligence pot ", " rolling soup ").Master controller this 5 width of cloth element picture combination, is presented at the relevant position on the M0 background picture by picture combination control command.
As shown in Figure 5, when the user selects other function button, during as " rolling soup " function, then need be updated to picture P1.Its disposal route is: relatively intend upgrading the background picture numbering of picture P1 and the background picture numbering of initial picture P0, both are M0, therefore need not to change; The element picture that needs to upgrade is positioned at the K1 district, and relatively the element picture of K1 district plan renewal " rolls soup " and the pixel of finite element picture " Baoshang ", and both are identical, then directly uses the new element picture " to roll soup " and covers finite element picture " Baoshang ".
From the foregoing description as can be seen: if a certain pictures, all show button element picture in K1~K10 zone, when pressing K1~K10 zone selection function, the picture that needs to upgrade all adopts the same background picture, only need be combined into the picture that a pictures can be finished 10 button necessary operations display interfaces.And if the mode that picture routinely shows is operated promptly as long as the show state difference of any one key area then needs to call the new picture of a view picture, present embodiment only need be combined into 10 width of cloth pictures.
The present invention can significantly reduce the quantity of combination picture, thereby reduces the requirement to system storage capacity, significantly improves the refresh rate of picture, reduces the requirement to system running speed, thereby reduces cost of products.
