Embodiment Construction

[0055] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0056] Such as figure 1 As shown, a product to be inspected includes an LCD display 102 and a camera 101 above it. The present invention utilizes the characteristic that the product to be tested has a camera 101 and an LCD display 102 at the same time, and utilizes simple external equipment, such as figure 2 A mirror 103 is shown as a reflective mirror surface, so that the camera 101 of the device under test can obtain the output image of its LCD display screen 102 through the mirror surface 103 . Here, by adjusting the positions of the product to be inspected and the mirror surface 103 , the camera 101 can completely capture the display area of ​​the LCD display screen 102 . .

[0057] Such as image 3 As shown, the image output from the LCD display screen 102 fed back from the mirror 103 passes through the camera 101 , the...

Abstract

The invention discloses a self-test method for an LCD display with a camera, which comprises the following steps: reflecting an image displayed by an LCD display to be tested into the lens end of a camera to be tested; and receiving and analyzing image data output by the camera to be tested, and judging whether the LCD display to be tested and the camera to be tested have defects in quality. The invention can improve the testing efficiency, and simultaneously unifies testing standards.

Description

technical field [0001] The invention belongs to the field of consumer electronics, and in particular relates to a self-inspection method for an LCD display screen with a camera. Background technique [0002] Existing communication terminal equipment, such as video intercom terminals, mobile Internet devices (MID) and mobile phones, usually include devices such as LCD displays and cameras. During the production process of products, for cameras and LCD displays, etc. For important components, the quality of their raw materials and assembly methods and processes will affect the quality of the final product. A common practice in the industry today is to add some inspection stations to the production line to judge the quality of device assembly through manual inspection. [0003] However, manual detection has many disadvantages: subjective judgment is prone to errors, and at the same time, people are prone to fatigue, the standard of judgment is uncertain, and the detection time...
