1.2 Given a scenario, install components within the display of a laptop

OLED Monitor

- organic LED display uses a layer of organic material that responds to electrical stimulus to emit light. This process allows each pixel to light individually, resulting in much deeper black levels than LED. OLED displays are also thinner and lighter than LED displays.

LCD monitor

A computer monitor that takes advantage of the polarizing properties of liquid crystals to produce images on a screen. Most LCD are TFTs.

Thin Film Transistor (TFT)

A technology for LCD displays in which transistors are positioned at each pixel.

Which monitor technology requires an inverter to convert DC back into AC? A) LED B) CCFL C) OLED

B) CCFL

LCD Disadvantages

Black Levels, Separate Backlight (Florescent, Led, Ect), Difficult to replace.

CCFL

Cold Cathode Fluorescent Lamp

OLED Disdvantages

Degrades over time, Decayed images can remain on screen, more costly and power hungry

What is a symptom of a worn out backlight?

Dimmer screen than before, or a reddish/ pinkish hue to the screen, or maybe a loss of color.

What is the cause of intermittent lines on the laptop screen?

Display cable needs to be reconnected or replaced

LED monitor

LCD monitor that uses LEDs instead of CCFL tubes for backlighting, creating much higher contrast ratios and image quality.

LCD Layers

Light Source -> Polarizing Filter -> Electrodes -> Liquid Crystal -> Electrodes -> Color Filter -> Polarizing Filter -> Display Surface

LCD Advantages

Lightweight, Low power, Inexpensive

Where is the laptops microphone located?

Near the Web camera, often apart of the webcam module.

How do you easly identify M.2 and Mini PCIe card?

One screw (for M.2) or two screws (for Mini PCIe).

OLED

Organic Light Emitting Diode

Which ways can a webcam be disabled?

Removed, disabled in the operating system, or via a function key.

OLED Advantages

Thin & lighter, no back light, good black levels

True or False? Digitizer overlays are available for laptops displays that are strapped onto the display and connect via USB?

True
