Character element displays have been widely used in devices such as screen displays (OSD), pagers, and mobile phones. Due to the structural limitations of these devices, they all use low-memory RAM, ROM, and fast memory. Flash memory. The previous character element display, under the DOS environment of the PC system, is mostly displayed in Mono text mode, which uses a font code to indicate a predetermined font in the text set, and a font attribute to indicate Font type. The required memory space, as shown in Figure 1 for the traditional single text mode OSD device, the 10 address setting of the above graphic display is divided into 15 rows (rows) and 30 columns (columns), so the entire The playback screen is divided into 15 × 30 〇SD blocks, and each 〇SD block uses 8bit to display with 256 fonts, so the required capacity of the display memory must have 8 * 15 * 30bit, in addition to 0SD On the font code storage, as shown in the first figure below, 16 pixels and 16 lines are used to display a specific character, such as 256 fonts such as A, B,. · 0, 1, etc., so 256 * 16 * 16bit memory capacity is required. Since the memory capacity of the above two is not much, it is very suitable for devices such as pagers and mobile phones. However, as consumers ’requirements become higher and higher, the use of monochrome text mode display is no longer sufficient for personal needs. Instead, they have character elements with color specifications such as VGA color display. To choose the type of font, and to define the color of the front and back background 3 This paper size applies the Chinese National Standard (CNS) A4 specification (21〇X 297 mm) ------------- ^ ^ -------- Order --------- line (Please read the note on the back?

(Color) Therefore, in consideration of color fonts, it is necessary to multiply the memory capacity. Comparing with the traditional single text mode in Figure 1, the capacity required for memory is shown above. The same is 8 * 15 * 3〇bit, but the SD font code is stored below the figure 1 except that it uses a 16-pixel dot and a 16-line code to display a K-determined character. For each character color Use 4 others (take 16 colors as an example), so you need 256 * 16 * 16 * 4bit Memory capacity of the body, if the front and then added 1, under consideration of the color change of the background, will significantly increase the memory capacity cunning 'This display uses less memory capacity, there will be insufficient information storage case. The other is to use a PC window environment to display color graphics in graphic mode. It directly uses bit mapping to display pixels, so there is no need to test the front and back backgrounds, but it must be used in each OSD block. Considering the change of the entire display color, the graphic OSD using bit mapping shown in Figure 2 requires a total of (30 * 16) * (15 * 16) * 4 bits of memory capacity, where 4bits are for each Each character uses a color change, so more memory capacity is needed. In addition, when the entire system is switched, the entire screen must be converted, so several display screens must be stored in advance. You need the multiple of the above (3Pl6) * (15 * 16) * 4bit memory capacity, plus When switching screens, it also runs very slowly due to the large memory load. In view of this, the object of the present invention is to provide a background mapping display method. For the above two color display modes, it is necessary to consume a large amount of memory, storage capacity and excessive memory capacity, and use monochrome fonts and colors. The background combines display and loading changes separately to reduce the amount of memory storage and reduce changes in system loading content.

Description of the invention (3) The present invention provides a background mapping display method, which is suitable for use with a display with a small memory storage, wherein the display is composed of a plurality of Firstly, a first memory is used to store a plurality of monochrome fonts, and then a second memory is used to store a plurality of colored backgrounds, and then a third The memory is used to display the monochrome font of the first memory and the color background of the second memory on the display, and the monochrome font and the color background can be loaded at any time. The display may be a pager, Mobile phones, PDAs, OSDs, subtitles, watches, electronic dictionaries, video player display panels, home appliance display panels, electronic bulletin boards and other information players or video subtitles, as for the first memory, the second memory, and the third memory Can use RAM, ROM, flash memory, etc. In order to make the above and other objects, features, and advantages of the present invention more comprehensible, preferred embodiments are described below in detail with the accompanying drawings, as follows: Brief description: Figure 1 shows the OSD device diagram of the traditional single text mode. ^ Figure 2 shows the graphic format using bit mapping.

Because color fonts must be used to increase the memory capacity multiple times, a display with less memory capacity will generally have insufficient data storage. As for Using a PC window environment to display color changes in a graphical mode, the bitmap is directly used to display pixels, so for each OSD block, the entire display color change must be considered, so it is more important for memory Significant burden on mass storage, coupled with loading of pre-stored memory capacity required for screen switching, will also cause slow operation. Therefore, the present invention takes into account the above-mentioned two color display modes, and considers the actual use requirements. For general users, only a single color system is required for the font display, and in accordance with the color change of the background color, it is monochrome. Fonts to reduce the consumption of large memory storage. As for the front and back backgrounds, although there are many color variations in the design, because the patterns are almost the same, we only need to store some colored backgrounds to display them in a repeated manner. In the present invention, a combination of a monochrome font and a color background is used to display and load separately. We can effectively reduce the memory storage and reduce the system load. ---- Order --------- line (please read the precautions on the back before filling this page) This paper size applies to China National Standard (CNS) A4 (210 X 297 mm): / 006525137 A7 B7 617 4 twf.

Then, please refer to Figure 3, which shows a schematic diagram of the scene map display of a kind of scene map according to a preferred window embodiment of the present invention. In order to further compare the advantages of the reverse mapping display architecture of the present invention, we use Figure 4 and Figure 5 to illustrate the use of color fonts for graphic screen display and bitmap mapping OSD. Comparison. The above screen display can be pager, mobile phone, PDA, OSD, subtitle machine, watch, electronic dictionary, video playback #series panel, home appliance display panel, electronic bulletin board and other information players or video characters: etc. In Figure 3, we use K as the number displayed in the window, such as the above It is divided into 15? [J (rows) and 30 columns (columns), so that the entire playback screen is divided into 15X30 OSD blocks, so we include K display codes in the display code buffer 20 for the selection of the entire screen font Then, we select a plurality of monochrome fonts stored in the first memory 22. Here, we use Fs as the font set size (for example, 256), and M * N as each 0SD area. Block pixels (for example, 16 * 16). In addition, we use the second memory 24 to store multiple color backgrounds. Since we set the front and back backgrounds to require Ts, respectively, plus the pixels of each 0SD block are M * N, and we use 4bit (using 16 colors as an example) as the depth change, so we can get the required memory storage of the front and back backgrounds are Ts * M * N * 4, and then the second memory 24 To store a plurality of color backgrounds and a plurality of monochrome fonts stored in the first memory 22, and combine them with the background mapping effector 26 to transmit to the display 28 to display the color backgrounds and monochrome characters in the third internal memory; Type, and can be monochrome font and color at any time -------------- --------------- ^ (Please read the notes on the back before filling out this page) Printed on the paper by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, China Paper Standards (CNS) A4 Specifications (210 X 297 mm) 525137 A7 B7 6174twf.doc / 006 V. Description of the invention (ζ) Background loading changes. The above-mentioned first memory, second memory and third memory can use RAM, ROM, fast memory The sum of flash memory and foreground and background have any one of the three or more pattern generation mechanisms, and store the predefined patterns in any of compressed and uncompressed formats. Next, in Fig. 4, we explain the graphic display structure of color fonts. Here, the same parts are used with the same symbols. For example, the display code buffer 30 contains K display codes to select the font of the entire screen. Then, after selecting the memory 32 with color fonts, it must have Fs inside. * M * N * 4 (where Fs is, for example, 256), which will occupy a large amount of memory, which is much larger than the method of the present invention, and finally transmitted to the display 34 with K characters. In FIG. 5, a bitmap map SD is used. We can see that it includes a number of K * M * N * 4 mappings on 40 pages. One of them is the main one and is projected on the display 42. The other pages are used to quickly switch the screen and K is displayed on the display window. Unit, where K is the display code of 15X30 0SD blocks, so that the entire memory storage capacity will be (K * M * N * 4 * pages) bits, which greatly increases the memory storage capacity. In order to further compare the burden of the memory storage used by the three, we will use the following Table 1 to explain: This paper size applies the Chinese National Standard (CNS) A4 (210 X 297 mm) (Please read the back Please fill in this page for the matters needing attention) -------- Order --------- Line 1 Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs Consumer Cooperatives 525137 6l74twf.doc / 006 A7 B7 Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the employee consumer cooperative V.

As for the display of the color font of the second type and the background map display of the third type, Fs * 4 * M * N and (Fs + Ts * 4) in the size comparison, Ts is the number of prepared color backgrounds, the general number is, for example, 2 to reserve the number of switches, as for Fs is the number of font sets, for example, 256, so Fs * 4 * M * N will be much larger than (Fs + Ts * 4), so the background mapping display of the present invention will effectively reduce the burden of storing memory. Then, in the right part of the table, for the comparison of the system stylized loading part, we can see that the first kind of bitmap has K 値 multiplied by M * as long as the screen is not changed or the background is changed.
