Bit Depth, aka Color Depth, describes the amount of information stored in each pixel of data. As you increase bit depth, you also increase the number of colors that can be represented. In the case of an 8-bit image, each pixel has 8-bits of data per color (RGB), so for each color channel the pixel has 28 = 256 possible variations. 10-bit would give 210 = 1024 color variations and 12-bit 212 = 4096.

Common anode means that the anode (positive) side of all of the LEDs is electrically connected at one pin, and each LED cathode has its own pin. Common cathode means that the cathodes of all of the LEDs are common and connected to a single pin. The anode for each LED has its own pin. Common cathode will save power consumption (up to 30%), will decrease the screen temperature (up to 25%) and will make electronic components more reliable at relatively low temperatures, resulting in a longer life span.

The moiré patterns or moiré fringes are large-scale interference patterns. For the moiré interference pattern to appear, two patterns must not be completely identical, but rather displaced, rotated, or have a slightly different pitch, like between camera and LED screen.

Video or image jitter occurs when the horizontal lines of video image frames are randomly displaced due to the corruption of synchronization signals or electromagnetic interference during video transmission. Jitter can cause a display monitor to flicker.

Ghosting on LED screens is an image artifact where pixels will light up with neighboring pixels when they are not supposed to be lighting up. In general, it is caused by an undesired current, mostly introduced by the parasitic capacitance, that will light up the neighboring pixels.
