<p>To put it simply, the <a href="https://www.genyulcm.com/products" rel="noopener noreferrer" target="_blank">LCD module</a> is a display screen plus a backlight assembly. For example, the display component of an LCD TV is a liquid crystal module, and its low temperature is equivalent to the picture tube in a CRT. The other parts of the liquid crystal module include power supply circuits, signal processing circuits, etc., and of course the housing. Today, Genyu will briefly introduce the contrast and brightness of LCD modules.</p><p><br></p><p>Contrast of LCD module</p><p>The control ICs, filters and oriented films used in the manufacture of LCD panels are related to the contrast of the panel. For general users, a contrast ratio of 350:1 is sufficient, but in the professional field, such a contrast is not enough. Meet the needs of users. Relative to CRT monitors easily reach a contrast ratio of 500:1 or even higher. Only high-end LCD monitors can achieve this level. Since the contrast is difficult to accurately measure with the instrument, you have to look at it yourself when you choose.</p><p><br></p><p>The brightness of the LCD module</p><p>Liquid crystal is a substance between solid and liquid. It cannot emit light by itself and requires additional light sources. Therefore, the number of lamps is related to the brightness of the liquid crystal display. The earliest liquid crystal displays had only two upper and lower lamps. Up to now, the lowest of the popular type is four lamps, and the high-end one is six lamps. The four-lamp design is divided into three types of placement: one is that there is a lamp on each of the four sides, but the disadvantage is that dark shadows appear in the middle. The solution is to arrange the four lamps from top to bottom. The last one is the "U"-shaped placement, which is actually two tubes produced by two lamps in disguise. The six-lamp design actually uses three lamps, and the manufacturer bends all three lamps into a "U" shape, and then places them in parallel to achieve the effect of six lamps.</p><p><br></p>
