A bright dot defect or hot pixel is a group of three sub-pixels (one pixel) all of whose transistors are "off" for TN panels or stuck "on" for MVA and PVA panels. [2] This allows all light to pass through to the RGB layer, creating a bright pixel that is always on. Another cause of bright dot may be the presence of impurities in the liquid crystal.
When the TV displays the left eye image, the glasses block the signal of right eye image by closing the shutter of right glass lens. By contrast, FPR 3D shows the images of left-eye and right-eye simultaneously, dividing the images into right-eye and left-eye by the correlation between FPR film on panel surface and polarizing glasses.
Burn-in on a monitor, when severe as in this "please wait" message, is visible even when the monitor is switched off. Screen burn-in, image burn-in, ghost image, or shadow image, is a permanent discoloration of areas on an electronic visual display such as a cathode-ray tube (CRT) in an older computer monitor or television set.
Detail of a TFT display showing whole screen persistence artifacts TFT display showing persistence artifacts Image persistence on a BenQ GW2765HT IPS LCD monitor. Image persistence, or image retention, is a phenomenon in LCD and plasma displays where unwanted visual information is shown which corresponds to a previous state of the display.
Televisions that use a combination of an LED backlight with an LCD panel are sometimes advertised as LED TVs, although they are not truly LED displays. [1] [2] Backlit LCDs cannot achieve true blacks for pixels, unlike OLED and microLED displays. This is because even in the "off" state, black pixels still allow some light from the backlight ...

After building it, he saw many problems that had to be corrected including major light losses and very noticeable pixels (sometimes referred to as the "screen-door effect"). He then invented new optical methods to create efficient and bright projectors and invented depixelization to reduce the screen-door effect.
