Description

Mini LED lighting detection jig

Technical Field

The application relates to MINI/MicroLED detection technical field, in particular to MINI LED detection tool of lighting a lamp.

Background

With the higher demand of the high-level TV market for image quality, the improvement of display image quality becomes a new demand of the high-level TV. Currently, 8k OLED (Organic Light-Emitting Diode) is limited by the problems of compensation circuit, IGZO (indium gallium zinc oxide) back plate technology and driving design, and still needs to be developed. The Mini LED is a brand new display technology, and has advantages in brightness and power consumption compared with the OLED and the duml cell (dual core display).

The difference between the Mini LED backlight and the conventional backlight is: the Mini LED can achieve millions of levels of contrast by local dimming zone dimming. When the traditional backlight is turned on, all the lamps are turned on, and the area which is not displayed on the panel is also irradiated by the backlight, so that the dark is not black enough, and the contrast is low. And the Mini LED can be matched with the display picture of the panel to realize area-on backlight, and the area backlight which is not displayed on the panel is not turned on, so that a complete black state is realized, and the million-level contrast is achieved.

However, because the Mini LED panel is greatly different from the conventional LCD panel lighting method, the conventional LCD panel lighting detection apparatus cannot be applied to lighting of the Mini LED lamp panel.
