Description of the invention (5) Invention reduction: (Please read the precautions on the back before filling out this page) The present invention relates to a device and method for screen display (OSD) 'Special It relates to a device and method for storing screen display fonts by using a flash memory (Flash ROM). 5-2 Inventions of the past: P digital display (Digital Monitor) gradually replaced the traditional analog display (Anal〇g M〇nit〇r) in the past, becoming the mainstream display on the market. The body circuit element becomes one of the important elements of the display. 0SD is mainly used to adjust the contrast, brightness, vertical and horizontal geometric size and position of the display screen, so that the display device 'has the best display mode. Traditionally, the OSD system uses the font read-only memory (Mask ROM) to store OSD fonts. Not only does it take a long time to make prototype samples, but if an OSD font production error occurs, the mask must be re-made, resulting in Delays in delivery have deprived monitor manufacturers of good business opportunities. In addition, 〇SD should be applied to different monitor models or monitor manufacturers, and the font size will change accordingly, thus increasing the difficulty of OSD component scheduling and stocking. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. In addition, the access speed of flash memory is usually slower than that of traditional font read-only memory. Therefore, traditionally, only TVs are suitable for using flash memory to store 0SD fonts. The reason is that the horizontal frequency of the TV is low, about 15.625khz. If you take a resolution of 10,000 points (Dot) as an example, , The highest OSD font pixel output rate is only 15Mhz (15khzx 1 000 = 1 5Mhz), the access time of commonly used flash memory 1 This paper size applies to China National Standard (CNS) A4 specifications (210 X 297 public A7 B7 Five Inventions (40ns printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economics as an example, it is not a problem for the 0SD display. However, the current horizontal monitors on the market have a high horizontal frequency, so OSD's pixel output rate will be as high as 15 MHZ. Because the access time of the flash memory is greater than the font read-only memory. When using the flash memory to store 0 SD fonts, you must first face flash圯 Hidden cylinder has a long access time problem. # OSD font is 1 2 X 1 8 o'clock car must be within 12 output clocks (〇utpUt Ci〇ck), read from flash memory. Potato 1 9 in; AA, owed 丨 丨 Chapter 12 Wu Wu information, with The flash memory access time is 40ns as an example, and the calculation is as follows: The shortest output clock is 40/12 and 3.333ns, and the fastest output clock is 1 / 3.333ns and 30OMhz. It can be seen that the output clock is still higher than Generally, the pixel output rate of SD is the same as the above i 50Mhz, so the access time of flash memory is not a problem. 'But for fonts with frame (B〇rder) and shadow (Shad_), As shown in Figure 2C and Figure 2D. The font data of the four points above, below, and left of any point in the 12X18 point matrix must be read in order to obtain the border and shadow. Therefore, it is necessary to read the 12-bit data of the previous line and the 12-bit data of the next line, cooperate with the 12-bit data of the line itself, and then process it by the central processing unit to form a Border font. And the effect of the shadow font, that is, within 12 output clocks, the CPU must read 3 pieces of i 2 bit data from the flash memory, a total of 36 bits of data 'each The reading time that can be allocated to the data is 4 output clocks, each of which has a shortest output clock of 40/4: 1 0113 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) (Please read the note on the back?
