Usually our laptop is CCFL (cold cathode fluorescent tube) backlit LCD (liquid crystal)
Usually our laptop is CCFL (cold cathode fluorescent tube) backlit LCD (liquid crystal)So we usually call CCFL backlit LCD LCD for short, while the new generation of LDE backlit LCD is called led for short. The concept is a little bit convoluted. I hope you take your time to read the following.The LCD with LDE backlight is thinner than that with CCFL backlight2. The LCD with LDE backlight can save power and the electro-optic conversion rate is about 99% higher than that with CCFL backlight. The electro-optic conversion of CCFL backlight LCD is 90%.3. The brightness of LCD with LDE backlight is higher than that of LCD with CCFL backlight. LCD with LDE backlight can be seen in the sun. The traditional CCFL backlight LCD brightness is relatively low, unable to view the screen in the sun.4. The LCD with LDE backlight has bright color, and the color gamut can reach 118%. The LCD gamut of CCFL backlight is only 78%.In general, you can't tell whether it's CCFL backlight or LED backlight, but you can see it in the sunlight. The LCD brightness of LED backlight is relatively high. It depends on whether the business is willing to let you take the notebook to the sun outside the mall for inspection.In addition, in order to save cost, some manufacturers now use the last generation of abrasives. Even the LDE backlight is the same as theCCFL backlight is as thick as LCD, so it can't be seen in appearance. If it is a new product, using a new abrasive, then the thickness of the screen should be 5 to 6 mm, 8 to 9 mm thinner than the CCFL backlight LCD screen.. I don't know the difference between high-definition colorful screen and LED backlight panel LCD wide screen, but I know that computers with the same configuration are generally more expensive with small screen size..
