FAQs (Frequently Asked Questions)

问:静态矩阵 LCD 和动态矩阵 LCD 有何区别?

答: LCD 若非由静态矩阵 格即由动态矩阵 格制作。动态矩阵的晶体管放在 每一像素交接点上,需少量电流即能控制像素的亮度。因此,动态矩阵显示器的 电流能够更加频繁的开关,增进屏幕刷新时间(例如,你的鼠标似乎在屏幕上滑 得更加平稳)。静态矩阵 LCD 具有一种导体 格,其像素位于 格的每一交接 点。

问: 与 CDT 相比,TFT LCD 的优势何在?

答:CDT 显示器中,一个电子枪以撞击荧光玻璃上的偏光电子方式发射电子和一

光。因此,CDT 显示器基本上以模拟红绿蓝信号操作。TFT LCD显示器则是运用 液晶屏面显示输入图像的装置。TFT与CDT有根本不同的结构:其每一晶胞皆有动 态矩阵结构和独立的活性元素。TFT LCD 有两个玻璃屏面,其空间装满液晶。当 每一晶胞接上电极并通上电压时,液晶分子结构则受到改变,从而控制从里面射 向显示图像的光。TFT LCD 比 CDT有多重优势,因为它能变得特别薄,又没有闪 光,原因是它不使用扫描法。

问: LCD 显示器的垂直频率为何最大只有 60 赫兹?

答:与 CDT 显示器不同,TFT LCD 屏幕具有固定的分辨率。例如,XGA显示器只 有1024x3(红绿蓝)x768个像素,而更高分辨率若无更多的软件处理则不可得。 本屏幕则定为 65赫兹点脉冲最大显示,即 XGA 显示器的标准频率之一。既然此 点脉冲是 60Hz/48kHz,此显示器的最大频率则为 60 赫兹。

问:现有何种广角技术?其功能如何?

答: TFT LCD 屏幕是透过液晶双重折射放进内部光亮的元素控制器/显示器。它 利用内部光折射至液体元素主轴的这一特性,控制内部光的方向、将光显示出 来。由于液晶上内部光的折射比率随光的内部角度变化,TFT 的视角比 CDT 的 视角更窄。通常,视角指对比度为 10 的角度点。目前有许多扩大视角的开发途 径。最常用的方法为利用广视角片,透过变换折射比率来扩大视角。IPS(面内 开关)或 MVA(多项垂直校准)也被用来扩大视角。飞利浦 181AS 型使用的则 是先进的 IPS 技术。

Computer Monitor specifications

Philips is renowned for its innovative technology and high-quality products, and its line of computer monitors is no exception. One standout product is the Philips computer monitor which combines sleek design with cutting-edge technology, making it a favorite among both casual users and professionals.

One of the main features of Philips monitors is their display quality. Many models boast Ultra HD or 4K resolution, providing stunningly sharp images and vibrant colors. With a high pixel density, users can enjoy an immersive visual experience that brings their graphics and videos to life. Additionally, Philips monitors often incorporate advanced IPS (In-Plane Switching) technology, which ensures wide viewing angles and excellent color reproduction, allowing multiple viewers to enjoy consistent image quality from various positions.

Another notable characteristic is the Philips Adaptive Sync technology, which eliminates screen tearing and stuttering during fast-paced gaming sessions. This feature enhances the overall gaming experience by synchronizing the monitor’s refresh rate with the frame rate of the graphics card, thus ensuring smoother gameplay. This makes Philips monitors an excellent choice for gamers who seek both performance and visual fidelity.

Philips does not compromise on user comfort either. Many models are equipped with LowBlue Mode that helps reduce eye strain by minimizing harmful blue light emissions, making extended sessions more comfortable. Furthermore, the SmartErgoBase design allows users to adjust the height, tilt, and swivel of the monitor, promoting ergonomic viewing positions that reduce the risk of posture-related issues.

Connectivity is another area where Philips shines. Most monitors come with multiple input options including HDMI, DisplayPort, and USB-C, providing flexibility for various devices. Some models also feature built-in USB hubs for easy access to peripherals, enhancing overall productivity.

Energy efficiency is also a hallmark of Philips monitors, with many models certified with Energy Star ratings. This commitment to sustainability ensures that users can enjoy cutting-edge technology without the guilt of excessive energy consumption.

In summary, Philips computer monitors are an excellent blend of high-resolution displays, advanced technologies, ergonomic designs, and energy efficiency, making them suitable for a wide range of users, from gamers to creatives. With their commitment to quality and innovation, Philips continues to establish itself as a leader in the computer monitor market.
