Professional analysis of large screen market mainstream LCD panel
The mature and development of LCD technology makes the LCD splicing screen into intelligent safe city command center, traffic management (Management) monitoring (Ji k a n o ng) terminal center, security industry monitoring center (Terminal) shows the best choice of equipment (Xu million N Z), liquid crystal display, large screen display system with the perfect HD (High Definition) (CH, ngxi of n) all kinds of graphic information to the user to bring the visual shock effect (Xi o, Gu I) and the stable operation of the system to achieve 7*24 hours of continuous work (g only ng Zu o) of high performance and rich (plump) products (CH million N P from n)'s series such as including 40, 46, 55 LCD, 60, 70, 82, 84, 98 the size of the narrow side series, ultra narrow series widely favored by the users (for love or respect)! LCD panel is currently on the market mainly is used in VA panel type It is a kind of panel type which is used in high-end LCD. It has high response speed and large viewing angle. Maintenance errors Samsung LCD splicing screen: a misunderstanding: with a soft cloth, glasses cloth or paper towel to wipe the LCD screen do not use glasses cloth and paper towels to wipe the LCD screen, LCD screen, it is easy to scratch the squeamish. There are two kinds of splicing screen, one is the traditional large screen display wall hard splicing technology, and the other is the use of edge fusion technology seamless seamless projector technology. Whatever people do or do is monitor display, display (zh million n sh.) information, the LCD panel is the best option.
In the market (SH ch million ng) mainstream panel has three main categories: V
A, TN and IPHOTOSHOP, each of which has its own liquid crystal materials and panel structures, has its own advantages and disadvantages.
A, VA type LCD panel: in the current display products is widely used (extensive), its biggest advantage (explanation: the favorable situation can overwhelm the other) feature is the visual angle (angle), with 16.7M color, there are MV
There are two types of A and PVA. Touch touch machine using infrared touch screen is the use of X, Y direction of the infrared matrix densely located to detect and locate the user's touch. The PVA is a panel type Samsung, in MVA (J ch panel based on the display performance, usually) (to output) output from the brightness and contrast are improved. In addition, Samsung will be the two types on the basis of extending the improved S-PVA and P-MVA two kinds of panel type, technology up to a higher level, wider viewing angle (angle), up to 170 degrees, faster response speed, can be controlled within 20ms.
Two, IPHOTOSHOP type panel: its advantages (y only u million Di n) is a visual angle (angle), color (smooth or delicate description, performance, looks relatively transparent and nuanced), which can also distinguish IPS PHILIPS liquid crystal display panel, a lot of use (SH from y o ng) are is the IPS type panel. S-IPS is the second generation of IPS technology, it has integrated the new technology to improve the IPS model (M SH) at certain angles of gray-scale reversal (reverse) phenomenon. LG and PHILPS's proprietary panel manufacturers (also known as manufacturers) are also featured by IPS as a feature of the LCD panel.
Three, TN panel: technically, compared with the VA and IPS type LCD panel slightly inferior. It does not show 16.7M gorgeous colors, only to 16.7M color (6bit panel), but the response time is easy to improve, the visual angle (angle) is limited. Due to the low cost and low price, it is mainly used in the entry-level and midrange products, but there are still many businesses selected.
