Laptop Attention – guard – tips articles: buy laptop computer screen should pay attention to the introduction of a number of matters. Net purchases by buying the following order, provide your reference.Note purchase laptop computer screenFor a laptop, the display is its “face” and “dignity” If anyone Guabu Zhu bad, but the laptop purchase, we often fuss (CUP, hard drives, memory) specifications, and ignore the quality of the LCD panel, which is really a great tragedy. Even if you noted in choosing laptop notebook screen, but it is also a general look at screen size, the availability of bright dark spots, while ignoring the other specifications of their LCD panels, such as the panel (type, true resolution, response time , visual angle) and so on. In fact, when purchasing notebooks, as a rational consumer, it should be noted that this right in terms of notebook computers, LCD monitor to use and you are the closest, and he’s good or bad can be a direct impact on your health and work, mood, therefore, from now on, you should pay attention to it, in order to pick a desirable laptop. Here we start from the most basic technical specifications to help you select the most suitable laptop computer screen.Panel TypeAt present the majority of the use of amorphous silicon notebook (TFT LCD a-Si Thin Film Transistor Liquid Crystal Display), some manufacturers directly on the surface for the different processing and display different characteristics, such as the IPS, MVA can increase the LCD TV’s perspective, contrast and color saturation. There are various other techniques Ge Jia, TFT LCD picture quality even more outstanding performance. Now a lot of notebooks on the use of a mirror SuperFine LCD screen, the screen coated with a layer of polyacrylic acid protective layer, LCD glass, like a multi-layer protection, but also adds texture.As for the recent low-temperature polysilicon LTPS often hear of the panel (LTPS, Low Temperature Poly-Silicon), the more active type liquid crystal is constructed with the manufacturing process are related to the amorphous silicon 10.4 Inch TFT LCD Touch Screen Monitor is not the same, except with high reflection, high brightness, low – reaction time, more energy-saving features, the number of panel joints can be reduced, but not with OLED organic light-emitting diode technology with, so LTPS panel (thinner, brighter, more energy-efficient). But at present LTPS panel process needs more than two or three mask, materials with relatively high manufacturing costs, primarily used in small and medium-size panels, panel more expensive than the average of about 20%. For example, Sony’s TX series is to use is such a LED screen.BrightnessLCD brightness in order to square candle or the NIT lumens as the unit cd/m2. Square candle called (NIT lumens), NIT generally used to indicate the brightness of LCD and CRT monitors. Lumens brightness is not a unit, but the luminous flux unit is equal to a uniform point light candles in the unit solid angle within a given luminous flux, it shows the strength of light. Of the desktop LCD market because of the number of backlight lamps more than a laptop LCD, generally brighter than the light notebook, about (200 NITS to 300NITS). In addition to the brightness comparison, the part of the low-cost LCD uneven brightness may occur the case, known as “Mura”, Center for high brightness, while the border region of low brightness, which result in poor image quality, and even distortion.ContrastContrast refers to the dark room, LCD full-bright white and black full-dark, the brightness of comparison between the two is the ability to present a rich color gamut LCD’s decision parameters, the higher the contrast ratio, screen layering the better. Even when viewing pictures of a high-brightness, dark parts of the details can be clearly presented.Response TimeLCD screen can show different angles of deflection, so that light generated through the screen images, the liquid crystal deflection angle of the need to impose a specific fixed voltage, each image will be reduced to 0 potential changes in re-raise, all of the rise time and fall time add up to a total reaction time, if the reaction time is too slow, would be that the images of the naked eye there is trailing. Generally speaking, 25ms millisecond response time is actually quite sufficient for the laptop, it’s not like the Touch Screen LCD desktop game performance, as the special emphasis on performance, so the general to the 16ms had enough.ColorEach point on the LCD are composed by the RGB three primary colors, a single color can have 256 colors performance (one color with 8 color performance, and therefore two of the eight parties, or 8 cubic), resulting in three 256 mixed color can be displayed three parties, 24 is 16,777,216 kinds of colors (16.7 million colors). The more the color of the performance, you can present a more subtle color screen. Color saturation level of that colorful screen, RGB three primary colors more vivid, the color LCD can display a wider area.
