Are the display signs of cultural relics in the museum capitalized in English?

Use all caps or capitalize the first letter.

The cultural relic display boards in museums are the same as ordinary billboards, following the principle of all capital letters or only the first letter.

The reason why there is a difference between upper and lower case is mainly due to the difference in writing methods and materials. All alphabetic scripts around the world originate from the Phoenician alphabet. This kind of letters are not case-sensitive at first. Many letters show abstract depictions of things, such as A is a bull's head and so on. Later, after various ethnic groups in Asia, Africa, Europe and other places learned this set of letters, they modified them according to their own languages. In terms of writing form, height is related to writing materials and tools. A typical example is Arabic. If you look closely at Arabic calligraphy, you will find that most of the strokes are relatively curved. Some of the same strokes are wide and light in color, and some are thin and dark in color. The reason is that the traditional Arabic writing instrument is a reed pen. This kind of pen is made by choosing a certain reed and drying it in the sun, then cutting a knife at the tip to guide the ink. Of course, similar to the classification of brushes into sheep hair, wolf hair, and purple hair, reed brushes also have a lot of particularities based on different materials, sizes, and production techniques. The combination of reed pens and paper makes Arabic calligraphy, like Chinese calligraphy, have a variety of fonts and calligraphers emerge in endlessly. The Latin alphabet was originally written on stone, cast in metal, or on a more precious carrier such as parchment. Therefore, it is often used for writing in more important places. At this time, capital letters give full play to their advantages of being solemn, clear, and easy to carve and cast. As for the disadvantage of being inconvenient for handwriting, it is not that prominent. Later, as writing materials became cheaper and cheaper, and the need for writing increased, lowercase letters were naturally used more and more. But many important things, such as proper nouns, are often still capitalized or capitalized. Among the squiggly lowercase letters, the "hard" uppercase letters will naturally stand out.
