FAQs (Frequently Asked Questions)

Q:How are LCDs made?

A:LCDs are created from two glass plates separated from each other at a distance of a few microns. The plates are filled with liquid crystal and then sealed together. The top plate is colored with an RGB pattern to make the color filter. Polarizers are then glued to both plates. This combination is sometimes called 'glass' or 'cell.' The LCD cell is assembled into a 'module' by adding the backlight, driver electronics and frame.

Q:What is polarization ?

A:Polarization is basically directing light to shine in one direction. Light is electromagnetic waves. Electric and magnetic fields oscillate in a direction perpendicular to the propagation of the light beam. The direction of these fields is called the 'polarization direction'. Normal or non-polarized light has fields in several directions; polarized light has a field in only one direction.

Q:What differentiates passive matrix LCDs from active matrix LCDs?

A:An LCD is made with either a passive matrix or an active matrix display grid. An active matrix has a transistor located at each pixel intersection, requiring less current to control the luminance of a pixel. For this reason, the current in an active matrix display can be switched on and off more frequently, improving the screen refresh time (your mouse pointer will appear to move more smoothly across the screen, for example). The passive matrix LCD has a grid of conductors with pixels located at each intersection in the grid.

Q:How does a TFT LCD Panel work?

A:On each column and row of the TFT LCD panel, a data source drive and a gate drive are attached, respectively. The TFT drain of each cell is connected to the electrode. The molecular arrangement of liquid crystal elements differ according to whether it is impressed with voltage or not. It varies the direction of polarized light and the amount of light by letting it through different arrays of liquid crystal elements. When two polarized filters are arranged vertically on a polarized light pole, the light that passes through the upper polarized panel is turned 90 degrees along with the spiral structure of the liquid crystal molecules and goes through the polarized filter at the bottom. When impressed with voltage, liquid crystal molecules are arranged vertically from the original spiral structure and the direction of the light is not turned through 90 degrees. In this case, light that comes through the top polarized panel may not go through the polarized panel at the bottom.

230w5 specifications

The Philips 230W5 is a standout monitor that embodies the blend of cutting-edge technology and elegant design, making it a compelling choice for both professional and personal use. Known for its superior display quality and ergonomic features, this monitor caters to various user needs, from graphic design to general computing tasks.

One of the most noteworthy characteristics of the Philips 230W5 is its 23-inch wide-screen display, which boasts a Full HD resolution of 1920 x 1080 pixels. This means users can expect sharpness and clarity that enhance the viewing experience, whether one is watching movies, playing games, or working on detailed projects. The monitor features an IPS (In-Plane Switching) panel, which provides wider viewing angles and more accurate colors compared to traditional TN panels. This ensures that the display looks vibrant and consistent from various angles, making it ideal for collaborative work environments.

The monitor is designed with Philips' SmartContrast technology, which dynamically adjusts the contrast ratio of the images being displayed. This results in deeper blacks and brighter whites, improving the overall visual quality, especially in darker scenes. Additionally, the PowerSensor technology is a remarkable feature that employs infrared detection to sense when the user is away from the monitor. It then automatically reduces the screen brightness to save energy, a blend of convenience and sustainability that appeals to environmentally-conscious users.

Ergonomics is another highlight of the Philips 230W5. The monitor comes equipped with height, tilt, and swivel adjustments, allowing users to customize their viewing experience to reduce strain during long hours of use. This is essential for professionals and gamers who are in front of the screen for extended periods.

Connectivity is also well-addressed, with multiple input options including HDMI, DisplayPort, and VGA, allowing for easy connection to various devices, from laptops to gaming consoles. The built-in speakers provide decent sound quality, further enhancing the multimedia experience without the need for additional external speakers.

In summary, the Philips 230W5 is more than just a monitor; it is a multifunctional device that combines impressive display technologies with user-centric features. Its Full HD IPS panel, SmartContrast, energy-saving capabilities, and ergonomic design make it a versatile choice for anyone seeking to upgrade their workstation or gaming setup without compromising on style or performance.
