Such as when program is play time, take out the program names of actual program inside the database can preserved from Set Top Box, then this program names is presented on the painting canvas of black background with white font, the height of this painting canvas is fixing, be 32, width is determined according to the length of actual programs name.
Based on step S102: save as array A a little by what show the described painting canvas of described Current Content, this step preferably adopts following steps to realize:
Step S301: from first point of painting canvas showing described Current Content, extracts the institute of described painting canvas a little one by one;
Step S302: the point of the described painting canvas that judgement is extracted is black or white;
Step S303: if the point of described painting canvas is black, this black color dots is stored in array A as numerical value 0;
Step S304: if the point of described painting canvas is white, this white point is stored in array A as numerical value 1.
Preferably, based on step S103: described array A is converted to the array of pixels B that can carry out showing on described OLED front panel, this step preferably adopts following steps to realize:
Step S401: by the capability value of described array A divided by 32 pixels, obtains the width value w of described painting canvas;
Step S402: by the 1st number of described array A, w number, w*2 number is until the result that obtained by shift operation of w*8 number is as the 1st number in array of pixels B;
Step S403: by described array A w*8+1 number, w*9 number is until the result that obtained by shift operation of w*16 number is as the 2nd number of described array of pixels B;
Step S404: by the w*16+1 number in array A, w*17 is until the result that obtained by shift operation of w*24 number is as the 3rd number of described array of pixels B, by that analogy, circulation w time is until be all converted into described array of pixels B by the number in described array A.
Preferably, after step s 103, before step S104, further comprising the steps of:
Step S501: judge whether the length of described array of pixels B is less than 128 pixels; If so, all fill numerical value 0 by described array of pixels B less than the length thereof of 128 pixels, to show black, if not, carry out roll display.
Based in step S501: carry out roll display, this step preferably adopts following steps to realize:
Step S105: when carrying out roll display, often before rolling one row, remove the first row that described OLED front panel shows, after the row that often roll, last row that described OLED front panel shows are replaced with the first row not carrying out the columns shown in described array of pixels B and shows.
Wherein, in rolling, what OLED front panel adopted is the mode of according to pixels rolling, and rolling smoothness will be better than VFD far away.This preferably adopts pixel rolling to carry out roll display, improves the smoothness of roll display, is convenient to check displaying contents.
Based on step S105: when carrying out roll display, often before rolling one row, remove the first row that described OLED front panel shows, often after rolling one row, last row that described OLED front panel shows are replaced with the first row not carrying out the columns shown in described array of pixels B and shows, this step preferably adopts following steps to realize:
Step S601: when carrying out roll display, before rolling, removes the displaying contents of first row on described OLED front panel now;
Step S602: the value that the 128th arranges is replaced by described array of pixels B the 129th number now, and shows;
Step S603: roll and continue, will now on described OLED front panel first row remove;
Step S604: after the row that again roll, replaces with the value of the 130th row of described array of pixels B, by that analogy, continues replacement process in this manner, realize roll display by the value that the described OLED front panel shows the 128th arranges.
Based on preferably above-mentioned, the Multi-language display method of the Set Top Box OLED front panel that the embodiment of the present invention provides, from the database of Set Top Box, obtain the Current Content needing display, wherein, described Current Content comprises multilingual character; Described Current Content is set to white, and the described Current Content of white is presented on the painting canvas of black background; The point of the described painting canvas that judgement is extracted is black or white; If the point of described painting canvas is black, this black color dots is stored in array A as numerical value 0; If the point of described painting canvas is white, this white point is stored in array A as numerical value 1.
Further, by the capability value of described array A divided by 32 pixels, obtain the width value w of described painting canvas; By the 1st number of described array A, w number, w*2 number is until the result that obtained by shift operation of w*8 number is as the 1st number in array of pixels B; By described array A w*8+1 number, w*9 number is until the result that obtained by shift operation of w*16 number is as the 2nd number of described array of pixels B; By the w*16+1 number in array A, w*17 is until the result that obtained by shift operation of w*24 number is as the 3rd number of described array of pixels B, and by that analogy, circulation w time is until be all converted into described array of pixels B by the number in described array A.Under the driving of described OLED front panel, by described array of pixels B, each is listed on described OLED front panel and shows successively in order, is shown as described Current Content.
Further, judge whether the length of described array of pixels B is less than 128 pixels; If so, all fill numerical value 0 by described array of pixels B less than the length thereof of 128 pixels, to show black, if not, carry out roll display.When carrying out roll display, before rolling, remove the displaying contents of first row on described OLED front panel now; The value that 128th arranges is replaced by described array of pixels B the 129th number now, and shows; Roll and continue, will now on described OLED front panel first row remove; Again roll after row, the value that the described OLED front panel shows the 128th arranges is replaced with the value of the 130th row of described array of pixels B, by that analogy, continue replacement process in this manner, realize roll display.Visible, the method adopts dot matrix display mode, realizes the multilingual display of set top box front panel, and according to pixels roll display is carried out in rolling, improves the smoothness of roll display, is convenient to check displaying contents.
Above the Multi-language display method of a kind of Set Top Box OLED front panel provided by the present invention is described in detail.Apply specific case herein to set forth principle of the present invention and execution mode, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection range of the claims in the present invention.
