What is CRT display technology?

[ Huaqiang Security Network News ] Nowadays, the display is everywhere, and its application is also very extensive. The development of the display has always been the focus of the development of the entire IT industry. Whenever the display has revolutionary products, it will often bring to the IT industry. A storm and a rush. Recalling the development process of the display industry in 2001, the flat-screen CRT and the LCD liquid crystal display can be said to have undergone a generational competition. In this competition, there is no such thing as a winner or a loser, and there is no such thing as the upper hand. A continuous marathon competition is underway with LCD LCD monitors. Faced with the trend of liquid crystal displays, CRT monitors show a mature pattern and maintain high cost performance to resist the replacement of liquid crystal displays. Although LCD LCD monitors have the advantages of one, they are in a shortage situation, and panel manufacturers are all busy expanding their production capacity. Solve the current situation of out of stock, However, before the advent of another wave of liquid crystal prices, the advent of high-brightness CRT displays can be said to be in a state of concern between flat-screen CRTs and LCDs. The original calm display market has become a hot spot in the market before the summer holiday season is coming.

What is CRT display technology?
High-brightness CRT displays are not strictly a technological breakthrough for CRT. Traditional TV sets have been used for many years in high-brightness applications. In the use environment of TV, the emphasis is on the performance of image images. Text is only an additional narration for TV; in terms of hardware structure, the field frequency of TV sets and The line frequency is 50Hz and 15Khz respectively. Compared with the minimum required 75Hz field frequency of the CRT display and the line frequency of 31Khz, the CRT display electron gun bears a large load, so the current of the electron gun is relatively small; in addition, the TV resolution requirement It is not as high as the CRT display, so the phosphor has a large dot pitch, and the phosphor luminous intensity is increased under a large current. The high-brightness CRT display is made possible by increasing the current that the electron gun can withstand and the lifetime of the phosphor coating, so that the CRT display can be developed with high brightness.

As far as CRT monitors are concerned, the past usage scenarios are biased towards word processing. If the brightness of the display is too large, the fonts tend to be imaginary at high resolution. However, with the popularity of the display on the network and multimedia, the use of single brightness , has been unable to meet the needs of consumers. The display must meet the various functional outputs provided by computers and other digital products. The development of displays has been extended from parametric competition to functional competition, and the experience demand for sensory entertainment has gradually guided the market.
In response, in June, BenQ launched a series of high-brightness displays, the first three high-brightness displays - 774P, 774PT and 781PT.

The 774P and 774PT have 110MHz bandwidth, 0.25mm dot pitch, and the highest resolution is 1280*1024@67Hz. It is enough for general DIY users. The 781PT has a high bandwidth of 176MHz, 0.25mm pitch, and the highest resolution. Up to 1600*1200@69Hz. Meet the high resolution and high refresh rate expected by gamers and computer enthusiasts. In addition to the MPRII certification, the 774PT and 781PT are certified by TCO99, making long-term users get the most. Good protection.

In terms of high-brightness function, BenQ provides the "SmartEye" hotkey, which provides switching between three common brightness modes - Standard, Internet, and Video. It is convenient for users to switch between different usage scenarios. In the network and video mode, the "SmartEye" hotkey blue light will be in the startup state. During the hotkey switching, the OSD menu will pop up, allowing the user to know the highlighted mode.

In the standard mode, the brightness of the display is suitable for the operation of common text editing, the emphasis is on the delicateness of the font and the precision of the focus; the network mode is useful for the user to browse the co-existing text on the Internet, in addition to the clear text content, the wonderful picture The picture quality is brighter in the high-brightness mode. The video mode provides a vivid picture of the TV, TV, and TV brightness required to play the game. In this highest brightness "recording" mode, the brightness can reach 330cd/m2, and the OSD brightness function key can be modified up and down in different brightness modes, so that the highest brightness can reach 340cd/m2. In addition, the OSD of the three monitors offers two preset color temperatures (9300K & 6500K) that provide standard mode cool and warm tones to suit different needs.

In addition, the value of these three monitors uses BenQ's “sharp color” technology of high-end display, which effectively reduces the image conversion time, reduces the interference of image signals, ensures the purity of colors, and makes the images more vivid and saturated. For the video mode, it can fully achieve the effect of the TV. However, under the standard mode, the “sharp color” technology combined with the dynamic focus switching circuit makes the lines appear more clear and detailed, so that there is no smear in the black line of the Excel table, which can provide the best text editing quality. . In general, these three high-brightness displays, regardless of function and parameters, can meet the needs of most consumers.

Nitrogen Trifluoride in the microelectronics industry is a kind of excellent plasma etching gas, which is cracked into active fluorine ion during the process of plasma etching. For the plasma etching of silicon and silicon nitride, using nitrogen trifluoride has higher etching rate and selectivity than using of carbon tetrafluoride or carbon tetrafluoride and oxygen mixed gas, especially in the process of etching integrated circuit material with the thickness of less than 1.5 μm, nitrogen trifluoride has excellent etching rate and selectivity, what's more, there is no pollution on the surface of etched material, it is also a good cleaning agent.
