Choosing Replacement LED LCD Screens for HP Mini Computers
Light-emitting diode (LED) and liquid-crystal display (LCD) screens are two methods of illuminating the viewing surface of a laptop. The light-emitting diodes and liquid-crystal technology work differently and have different features for watching videos and viewing still images. There are many sizes, features, and differences to consider when selecting LED LCD screens for HP Mini laptops.
What are the sizes and aspect ratios of the screens?The available sizes of the flat-panel screen viewing surfaces are 10.1 inches and 11.6 inches. Aspect ratio refers to the relationship of the image's width to the image's height. The expression is width:height. The available aspect ratios of the viewing surfaces are 5:4, 16:9, and 16:10.
What are the differences between liquid crystal and light diodes?Liquid-crystal technology is a flat-model surface that uses the light modulating properties of liquid crystals to show images, colors, shapes, characters, numbers, and letters that are still or moving. The illumination comes from a compact fluorescent lamp behind the panel. The lamps do not dim, but they illuminate quickly. Light-emitting diodes are semiconductor diodes that glow when they receive voltage. They are a subset of liquid-crystal technology. They use a blue, green, and red color wheel for showing colors and clear for showing white. The light-emitting diodes offer the capacity to dim or increase in brightness in small increments. The diodes are lighter in weight and smaller in size than the fluorescent lamps that illuminate liquid crystals.
How do you choose a replacement viewing surface for laptops?To select a replacement viewing surface:
- Measure the size of the viewing surface. It is measured in units of inches on the diagonal from the upper-left corner to the lower-right corner. Only measure the glass and do not include the frame or bezel in the measurement.
- Choose the technology: Select liquid crystal or light-emitting diode.
- Select the number of lamps: Liquid-crystal technology may use one or two lamps for illumination.
- Choose the type: Select a viewing surface that includes the connector cable and pins, bezel, or just the viewing surface.
Resolution refers to how many pixels per square inch are on the viewing surface. The higher the density, the more detailed the image. The available levels of resolution for the flat viewing surfaces are 1024 by 600 and 1024 by 768. The resolution may be adjustable in the computer's settings.
