AI Technical Summary

Problems solved by technology

The existence of the gap h will affect the accuracy of the measuring probe 12, because the ambient light of the outside world will enter the measuring probe 12 through reflection, and the non-seamless bonding between the measuring probe 12 and the curved display panel 11 will occur during multiple measurements. The combination will cause slight differences in the position of each measurement, which will reduce the accuracy of the measurement

Embodiment Construction

[0022] The present invention will be described in detail below with reference to the drawings and embodiments.

[0023] refer to figure 2 , In an embodiment of the measurement probe used for testing curved display panels of the present invention, the measurement probe includes a light guide cylinder 21 . The light guide tube 21 includes a first port 211 and a second port 212 which are connected.

[0024] Wherein, the first port 211 is used for connecting the color analysis device 30 , and the second port 212 is used for receiving the light emitted by the curved display panel 40 , so that the light is emitted to the color analysis device 30 through the first port of the light guide tube 21 . The color analysis device 30 detects the parameter values ​​of the curved display panel 40 according to the light received by the light guide tube 21 , such as brightness, color and other parameter values, so as to realize the detection of the curved display panel 40 .

[0025] Wherein, ...

Abstract

The present invention discloses a measuring probe and measuring system for testing curved surface display panel. The measuring probe comprises a light guide cylinder, and the light guide cylinder includes a first port and a second port which are conductive. The first port is configured to connect a color analysis device, and the second port is configured to receive a ray of light emitted by the curved surface display panel, wherein the end face of the second port of the light guide cylinder is arc-shaped in at least one direction. According to the invention, the accuracy of the test may be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a measuring probe and a measuring system for testing curved display panels. Background technique [0002] A curved display refers to a display with a certain curvature of the screen and a certain curved shape, which is usually obtained by bending a flat-panel display in a mechanical manner. Compared with flat-panel displays, curved displays have advantages such as better contrast, wider viewing angles, and immersive experience, making curved displays a new trend in the display market. [0003] Before the curved display leaves the factory, it usually needs to be tested, such as brightness, color and other display parameters, to ensure the factory quality of the curved display. During the detection process, the curved surface display is displayed, and then the light emitted by the curved surface display is obtained by the measuring probe, and the light obtained by the measuring p...
