How to enhance the effect of IC circuit

LCD monitors have been listed for nearly 10 years, it has completely replaced the traditional CRT monitors become the absolute mainstream of the market, we hereby ZOL monitor channel also launched a "basic display Hundred Questions" series of topics, from the subtle technical point of view as we opened one of these displays basic knowledge of secrets. We know that the color monitor LCD panel is to determine the effect of the main factors, while others will need to rely on the IC circuit part, in addition to controlling the accuracy of color reproduction, the manufacturers but also for everyday consumer use of adding a new feature, what are the main aspects of the function it?

Note: This series of topics for readers are new to the display, or want to learn the basics of the user display, if you think you have fully mastered monitor all kinds of knowledge, you can skip this confidence.

In the previous article, we have introduced the color LCD panel displays that affect performance results of the key factors, in addition to the display of the IC circuit is also a very important part, its main job is to "guide" LCD panel accurately show a variety of colors, in addition to the monitor according to the actual needs of manufacturers have joined the many new features.

● Dynamic Contrast technology

Dynamic Contrast is the first to come into contact with us through the IC circuit to control one of the technologies. For the lcd module, its response time and native contrast ratio is fixed, while the principle of dynamic contrast ratio is the IC chip will detect the contents of the screen, if the screen when it is found that most of the image is black, it will automatically issue a directive Let reduce backlight brightness, so that you can greatly reduce the brightness of the screen at this time, at maximum brightness remain unchanged at this time raised to 10,000:1 contrast ratio than we normally would this ratio is called "Dynamic Contrast" . The use of LED backlighting, the dynamic contrast ratio can reach 10 million: 1 or more.

With the popularity of LED backlight technology, the market dynamic contrast ratio LCD display once again been greatly improved from the previous 10,000:1 quickly raised to 100,000: 1 or even 10 million: 1. Dynamic contrast ratio enhancement can effectively increase the screen layering, and can slow down the display in all black screen light leakage, so consumers have the role of improving quality.

But when Dynamic Contrast is not necessarily the value the higher the better, when its value has reached a certain level, the improvement of its screen is no longer as 1000:1 to 10000:1 so obvious, so its value has continued to increase in significance not, so now despite the dynamic display manufacturers introduced a contrast ratio of up 100 million: graphic lcd display module 1 models, but did not apply this feature as the biggest selling point to publicity.
