As we all know, the notebook's screen size determines the size of a machine type, weight, and even design. As you heard most of the mainstream of 12.1,14.1 and 15-inch notebook, in which the size of the notebook's size is that screen size, rather than the size of the machine. Largely determines the size of the screen a certain type of machine performance and market position. 12.1 inches mostly 1-Spindle ultra-thin, thin and light machine. 14.1-inch mostly 2-Spindle design notebook. 15-inch All-in basically 3HD or models of.
Laptop LCD screen in a notebook occupies the entire cost of 1 / 3 share or so. Its production process and desktop LCD screen is almost the same, but the power supply module for the notebook's power consumption require special design.
Resolution of the LCD screen is a very important parameter. Now 12.1-inch screen resolution is also achieved XGA (1024 * 768) 14.1-inch LCD screen, full resolution of marching to SXGA, and UVGA and WXGA or 15 inch LCD screen of the world. In the same size LCD screen, higher resolution screen displayed more delicate. So buy a notebook, as far as economic conditions allow selection of high-resolution LCD screen.
In addition to concern for users of LCD resolution, but also know what type of LCD, LCD liquid crystal display usually HPA, DSTN, TFT three. DSTN is STN (super twisted nematic displays) to optimize the development of core technologies over the top, DSTN as dual scan technology, so the display is more delicate than the STN, more bright colors. The early notebook mainly use the LCD STN, DSTN since then the emergence, LCD and gradually switch to a DSTN LCD. STN and DSTN slower reaction time, usually around 300ms. Users can clearly feel the blur, and good at games and video are not now so perverted, so the general office user is acceptable.
As user requirements increase, STN, DSTN LCD gradually can not meet the user, so DSTN LCD manufacturers developed based on the HPA. HPA as fast DSTN, which is an improved DSTN. As the STN improved DSTN is the same. HPA can provide a better reality than DSTN quality, reducing the LCD response time, increase the LCD contrast and viewing angle, as it is DSTN improved over the production line changes very little, so the production costs and DSTN similar in price The above will reflect certain advantages.
Now the production of notebook LCD TFT screen is the most used. Is the thin film transistor TFT is used to actively control the amount of light through each pixel component. We have also called it "active-matrix thin-film transistors."
Color filter is composed of red, green, and blue color filters, a pattern of production in a large glass substrate. Each pixel (point) is a unit composed of three colors. If a panel resolution of 1280X1024, it actually has a 3840X1024 transistors and sub-pixels. ㄧ a 15.1-inch liquid crystal display (resolution 1024x768) the pitch of 0.3mm; and 18.1-inch liquid crystal display (resolution of 1280x1024) The dot pitch is 0.28mm. This also explains why the same size the higher the resolution the LCD, the screen will be more delicate, and brightness, contrast have different losses.
Notebook TFT-LCD brightness values are generally in the 150 ~ 200 cd/m2 (very few can reach 250 cd/m2). Although technically possible to achieve higher brightness, but that does not mean that the higher the better brightness values, because the high brightness of the display may make the viewer eye injury, but also will increase the power consumption of laptop battery use mode less time. Contrast is defined as the maximum brightness value (all white) divided by the minimum brightness value (black) ratio, the greater the ratio, this monitor is better. The LCD should be all black is not easy, but the backlight is always lit, followed by more or less there will be leaked. The human eye can accept a ratio of about 250:1 on.
Now we are increasingly concerned about, LCD response speed. I regret to tell you, because at this stage structural characteristics of the LCD itself, and technology development. Desktop LCD to enhance the reaction rate is the height of the crystal most of the voltage, the power consumption increases. This will reduce laptop battery mode in time. Laptop LCD response rate still at 20 ~ 30ms between. Most of the reaction rate in accordance with this notebook's LCD, or barely able to play CS, a class of games, DVD, or you can look at the
As individual notebook manufacturers have their own unique offerings of LCD technology, so that your notebook's LCD display with different characteristics, such as the notebook's LCD to be bright colors more. The high-end notebook in the ThinkPad FlexView Display170 used above degree viewing angle. Of course, everything can only let buyers choose.
