Description

Constant-temperature platform device for adjusting gamma value of OLED (organic light emitting diode)

Technical Field

The utility model relates to a constant temperature equipment field, in particular to constant temperature platform device for timing OLED gamma value.

Background

The OLED is also called a microdisplay, and has many characteristics such as small size, high resolution, microsecond-level response speed, and the like, so that the OLED is widely applied to the fields of VR, AR, EVF, FPV, film viewers, and the like. In order to make the display effect of the OLED more consistent with the visual habit of human eyes, gamma (gamma) adjustment must be performed after the OLED device is manufactured. The gamma curve is a special tone curve, and when the gamma value is equal to 1, the curve is a straight line having an angle of 45 ° with the coordinate axis, which indicates that the input and output densities are the same. Gamma values higher than 1 will cause the gray level of the output image to tend to be bright, and gamma values lower than 1 will cause the output to be dark; therefore, the display screen which is not subjected to gamma adjustment can affect the color brightness of the final output image.

An OLED gamma correction device disclosed in chinese patent publication No. CN104599633B includes: the device comprises a darkroom cavity, a DELTA manipulator, a color analyzer positioned at a DELTA manipulator terminal, an OLED device to be tested, a driving jig, a damping machine table, a signal generator, an industrial personal computer and a manipulator controller, wherein external light rays are prevented from entering the darkroom cavity; the signal generator outputs full white pictures from 0-order gray scales to X-order gray scales in sequence, the driving jig inputs signals output by the signal generator to corresponding electrodes of an OLED testing device to be tested, and the damping machine table is used for placing the driving jig; the industrial personal computer is used for controlling the signal generator, the color analyzer and the manipulator controller, storing and analyzing the measurement data, and finally burning the correction data into a drive IC of the OLED device to be tested.

Although the above-mentioned patent provides an OLED gamma correction device can adjust the gamma value of the OLED to a certain extent, in the process of gamma adjustment, the OLED itself generates heat to cause temperature variation, which leads to the problem of false gamma adjustment.
