In recent years, the development of LCD monitors has gradually taken a proactive position, and CRT monitors have suffered a tremendous impact. This article will focus on upgrading the LCD LCD monitor technology.
Since LCD LCD monitors and LCD TVs have a large number of similarities in the display principle, the respective fields of technology are influencing each other's development.
1. 120Hz technology In order to overcome the inherent smearing phenomenon of LCD, major LCD manufacturers have introduced 120Hz field frequency display. The monitor core processor has only 60Hz field frequency at the beginning. To achieve compatibility with the 120Hz screen, a frequency multiplier is used between the processor and the screen to achieve a field frequency change from 60Hz to 120Hz. Although this implementation achieves frequency multiplication, due to the need to increase frequency multiplication chips and the transmission and conversion of LVDS high-speed digital signals, the signal attenuation and signal-to-noise ratio are reduced, and the image quality after frequency multiplication is also affected. .
Now that the processor chip of the new LCD LCD monitor has realized the frequency multiplication function of the field frequency, the image frame response time is reduced and the response time is reduced by the 60 Hz scheme under the premise of guaranteeing the image effect through the interpolation frame method. Trailing phenomenon.
2, FULLHD technology With the progress of LCD technology, full HD LCD screen (physical resolution 1920 × 1080), as well as front-end camera, DVR, computer output digital HD signal, which makes the HDMI interface also appears in some high-end In the monitor. With front-end output devices such as cameras and DVRs with 1080P signal output, the output must be connected to a monitor with an HDMI interface. On the other hand, high-definition picture reproduction is possible. On the other hand, video and audio are all on one cable. In the transmission, the construction of the monitoring system is relatively simple. Such as Benson (Beso) LCD monitor, the LCD screen with a physical resolution of up to 1920 × 1080, with HDMI interface, can achieve full-HD signal point-to-point display.
3, USB local upgrade technology Due to the special nature of monitor use, various users use the scene and personal preferences are different, may need to adjust the different functions and effects for the customer's special requirements. Previous monitor upgrades required the use of specialized upgrade equipment and complicated upgrade procedures. Users were difficult to operate on their own. Today's LCD monitors are equipped with a USB upgrade function to solve this problem. The manufacturer only needs to provide the program according to the user's needs to the user. After the user copies the program to the U disk, the user can upgrade it by simply operating the remote controller, and can immediately confirm whether the monitor state meets the requirements. This avoids the inconvenience of communication between manufacturers and users. For example, for some products with USB upgrade function, the user only needs to insert a USB flash drive with a new program on the USB interface of the monitor. After a simple operation of the remote controller, the user can quickly upgrade in half a minute. Convenience.
4, DID / PID technology DID / PID is a kind of industrial standard Huai designed, can be a long time continuous operation of the LCD screen (24 hours a year 365 days boot), can adapt to the harsh working environment of the dedicated LCD screen. As its unique display technology, it is different from the ordinary liquid crystal display in that it improves the alignment structure of the liquid crystal molecules, and can be placed horizontally, vertically, and suspended ceiling. With high brightness, high definition (1080P), long life, stable operation and low maintenance cost, and its high color saturation (DID up to 93%, while the ordinary LCD screen is only 72%, reaching Higher contrast and brightness, and a long service life of 80,000 hours, such as some 40-inch, 42-inch, and 46-inch LCD monitors on the market are all using DID/PID technology LCD screens, plus some unique The software and hardware processing technologies make the LCD monitor more satisfying to the user's needs.
For the monitor industry, due to the price and performance limitations of LCD monitors, CRT monitors have occupied most of the market space. However, in recent years, with the rapid development of the market and technology, LCD LCD monitors are rapidly occupying all kinds of emerging monitoring applications. Due to the rapid development of LCD monitor applications and the shrinkage of the CRT monitor market, CRT monitors are facing the fate of front-end picture tube manufacturers, chip manufacturers and complete machine manufacturers. It is expected that in the next two years or so, the market will It is hard to find traces of CRT monitors.
At the same time, the future of LCD monitors will also face more challenges. It is believed that LCD monitors will continue to develop in the direction of high definition, high brightness, high contrast, low power consumption, long life, ultra narrow edges, and low price.
