Description

Technical Field

[0001] The present invention relates to the technical field of OLED display devices, and in particular to an organic display device and a calibration method. Background Art

[0002] Organic display devices refer to electronic display devices that use organic materials as light-emitting or display elements. Organic display devices are widely used in the field of consumer electronics due to their advantages such as self-luminescence, high contrast, wide viewing angle and flexibility. OLED and AMOLED dominate the high-end market. Among them, OLED is a display technology that is widely used in TVs, mobile phones, tablets and other devices.

[0003] However, in order to enhance the stability of the OLED screen during use, there is a patent document with a publication number of CN220870461U, which adopts the mutual use of the OLED screen body, the protective frame, the protrusion, the limit plate, the first clamping plate, the guide slot, the installation block and the installation block, so that the OLED screen is easy to position during installation with the screen installation clamping plate, so that the installation positioning effect is good. During installation, the protrusion arranged on the outer wall of the OLED screen body is inserted into the guide slot, and then the installation block is clamped in the protective frame, thereby realizing the installation positioning of the OLED screen body during installation, and improving the use effect of the device to a certain extent.

[0004] From the above-disclosed technical contents, theoretically speaking, the implementation of the relevant technical structure is conducive to the reinforcement of the OLED screen. However, according to the description in the above-disclosed technical contents, the OLED screen is limited by the installation block. Since the OLED screen has different thicknesses and sizes, and the size of the installation block itself is fixed, when the thickness value of the OLED screen is greater than the inner diameter value of the installation block, the OLED screen is difficult to be placed inside the installation block, making it difficult for the installation block to limit the OLED screen. When the thickness value of the OLED screen is less than the inner diameter value of the installation block, the gap between the OLED screen and the installation block is too large. After the installation block limits the OLED screen, the OLED screen may still shake in the installation block. After the OLED screen collides with the installation block, it is very easy to cause damage to the OLED screen, thereby affecting the service life of the OLED screen. Summary of the invention

[0014] A calibration method for an organic display device comprises the following steps: S1. Restrictions on the installation position of the OLED screen body; 1.1.

Since the spur gear is respectively engaged with the tooth patterns of the No. 1 and No. 2 ruler bars, the rotation of the spur gear drives the lateral movement of the No. 1 and No. 2 ruler bars.

The threaded rod and the connecting rod are connected by threaded sleeves. The threaded rod rotates in a circular motion and drives the horizontal motion. The threaded rod pushes the pressing plate toward the OLED screen body while the movement is in progress. This can limit the fixed position of the OLED screen body in the clamping plate, so that the position of the OLED screen body on the mounting frame can be calibrated. S2.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1.

When the threaded rod (16) moves, the pressing plate (5) is pushed toward the OLED screen body (1), thereby limiting the fixed position of the OLED screen body (1) in the clamping plate (4), so that the position of the OLED screen body (1) on the mounting frame (13) can be calibrated; S2, calibrating the OLED screen body (1); 2.

1. The cross-grained lines of the white light sight are located at the center of the grid-grained targets on the ITO glass transparent electrode layer, metal electrode layer, electron transport layer, hole transport layer, and light-emitting layer, and the horizontal and vertical lines of the cross-grained lines and the grid-grained targets on the ITO glass transparent electrode layer, metal electrode layer, electron transport layer, hole transport layer, and light-emitting layer are overlapped; 2.

2. Use the magnification detector to calibrate the magnification of the ITO glass transparent electrode layer, metal electrode layer, electron transport layer, hole transport layer, and light-emitting layer. The eyepiece on the magnification detector is consistent with the optical axis of the ITO glass transparent electrode layer, metal electrode layer, electron transport layer, hole transport layer, and light-emitting layer respectively; 2.

3. An infrared laser light source is used to emit an infrared laser beam, and the imaging of the infrared laser beam on the ITO glass transparent electrode layer, the metal electrode layer, the electron transport layer, the hole transport layer, and the light-emitting layer is observed.
