Problems solved by technology
[0014] In order to solve the above-mentioned problems in the prior art, the purpose of this disclosure is to provide a detection device and method for a display module, so as to overcome the failure of gamma correction to cause materials such as polarizers and glass cover plates to be unrecyclable, resulting in material costs and The problem of waste of time cost
In addition, this disclosure can also avoid the problem that only a single detection device can perform a single type of detection on the display module, resulting in low detection efficiency and consuming human resources.

The invention provides a detection device and method for display modules. The detection device comprises a platform, a T-shaped rod, a first colorimeter and a second colorimeter, wherein the platformis provided with a first detection area used for locating the first display module and a second detection area used for locating the second display module; the T-shaped rod is composed of a vertical rod and a transverse rod, the vertical rod is vertically fixed to the transverse rod and vertically arranged on the platform, and the transverse rod and a platform top of the platform are parallelly spaced; the first colorimeter and the second colorimeter are installed at the two ends of the transverse rod respectively, wherein the first colorimeter is used for detecting the first display module located on the first detection area, and the second colorimeter is used for detecting the second display module located on the second detection area.
Description
technical field [0001] The disclosure relates to a detection device and method, in particular to a detection device and method for a display module. Background technique [0002] Organic light-emitting diode (OLED) is a new type of active light-emitting display device, which has the advantages of ultra-light, ultra-thin, low power consumption, high brightness, high contrast, high resolution, etc., and is regarded as the successor to liquid crystal display (LCD) It is a new display technology with the greatest development potential after Plasma Display (PDP), and is widely used in TVs, smart phones, smart wearables, virtual reality (VR), automotive displays and other fields. [0003] For display devices, we generally think that the representation of light and dark should correspond to the corresponding brightness at equal intervals. However, in fact, the human eye is much more sensitive to brightness in a darker environment than in a bright environment. The relationship curv...
