<p>Brightness of dot matrix lcd</p><p>A <a href="https://www.genyulcm.com/dot-matrix-lcd" rel="noopener noreferrer" target="_blank">dot matrix LCD</a> is a substance between solid and liquid, which cannot emit light by itself. It requires an additional light source. Therefore, the number of lamps is related to the brightness of the LCD. The earliest LCD monitors had only two lamps on the top and bottom. Up to now, the lowest popular type is four lamps, and the high-end is six lamps. The four-lamp design is divided into three placement forms: one is that there is a lamp on each of the four sides, but the disadvantage is that there will be a black shadow in the middle. The solution is to arrange the four lamps from top to bottom, The last one is the "U"-shaped display, which is actually two lamps produced by the two lamps in disguise. The six-lamp design actually uses three lamps. The manufacturer bends the three lamps into a "U" shape and places them in parallel to achieve the effect of six lamps.</p><p><br></p><p>Response time of dot matrix lcd</p><p>The response time of the dot matrix LCD refers to the response speed of the LCD display to the input signal, that is, the response time of the liquid crystal from dark to bright or from bright to dark, usually in milliseconds (ms). To make this clear, we need to start with the human eye's perception of dynamic images. There is a phenomenon of "visual residue" in the human eye, and the high-speed motion picture will form a short impression in the human brain. Animation, movies, etc. until now the latest game is the application of visual residue.</p><p><br></p>
