Image Processing
TVs usually watch fast-changing motion pictures. The image processing capability of still pictures is poor. Most of the monitors are mainly still pictures. Therefore, the monitor is more professional in image processing. The professional LCD monitor has bandwidth compensation and Improve the circuit, the video bandwidth reaches 20M, the sharpness is greatly improved, professional 3D digital comb filter, enhanced brightness, chroma digital noise reduction processing capabilities, enhanced motion detection capabilities, significantly improve the smoothness of the edge of moving images, greatly improving The sense of hierarchy of the picture can better express the details and make the picture more delicate and natural.
Color reproduction
If the definition is mainly determined by the amplitude-frequency characteristics of the video channel, the degree of reduction is mainly determined by the chrominance signals of the three primary colors red (R), green (G), and blue (B) and the phase of the luminance signal in the monitor. Decided. Since the monitor usually observes static images, the requirement for monitor color reproduction is higher than that of TVs. Therefore, professional LCD monitors should have accurate compensation for brightness, color processing, and R, G, and B processing. Circuits and delay circuits to ensure phase synchronization of light/color signals and R, G, B signals.
Overall stability
When a monitor forms a closed-circuit monitoring system, it usually needs 24 hours a day and 365 days of continuous power-on use each year (while TVs usually only work for a few hours each day), and some monitors may have a poor application environment. Requires higher reliability and stability of the monitor. Compared with televisions, in terms of design, the monitor's current, power consumption, temperature and resistance to electrical interference, the ability and margin of electrical shock, and average time between failures are much greater than those of televisions. At the same time, the monitor must also The use of a fully shielded metal shell ensures electromagnetic compatibility and interference performance; in the selection of components, the characteristics of the components used in the monitor, such as voltage resistance, current, temperature, and humidity, are higher than those used by the television; In the installation and debugging, especially the components and the aging process requirements of the whole machine, the requirements of the monitor are also higher. The aging of the whole television during the television manufacturing is usually about 8 hours at the normal temperature on the assembly line, and the whole machine of the monitor Aging requires aging for more than 24 hours in the aging pipeline of a high-temperature, high-humidity, sealed environment to ensure the stability of the entire machine. Components used in televisions are not suitable for continuous use without interruption. If you force the use of a TV as a monitor, it is prone to malfunction. If it is severe, it may cause an accident due to the high operating temperature of the TV.
Signal cancellation principle of intelligent digital image sticking <br> <br> intelligent image processing chip will eliminate the blur function of the inputs is monitored continuously, according to the root mean square value of each frame of image signal is input to judge whether the image is a still Image or dynamic image, the RMS value reflects the average brightness level and light-dark distribution of the input image. From this parameter we can determine the characteristics and differences of each frame of the input signal, if the input image is still for a period of time. After the image, the system activates the residual image engine. This engine automatically moves the format of the input signal according to the static or active state of the input image, so that the position of the input image on the screen produces a slight and rapid change. The long-term, no-change control of the liquid crystal molecules, and the long-term, static control voltage for the liquid crystal molecules is just the root cause of the afterimage generated after the liquid crystal screen displays a long-time still image. After the rapid and minor transformation of the still image input by the residual image engine, the liquid crystal molecules have a chance to breathe for a certain period of time, thereby avoiding permanent damage to the liquid crystal screen and achieving the purpose of eliminating ghost images.
