Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] see figure 1 , an embodiment of the method for measuring the reflective intensity of the display screen surface of the present invention includes:

[0025] Step 101: Obtain the brightness values ​​of the first screen and the second screen placed in the same environment for display. The observation brightness of the first screen and the second screen is the same, and there are shading objects around the front of the first screen. The first screen and the second screen have the same brightness. The second screen is placed side by side;

[0026] The screen is a screen of a display device, and most screens of existing display devices are made of reflective materials, such as glass. The first screen and the second screen in this embodiment may be screens of a general display, which are also objects to be measured or used in this embodiment of the ...

Abstract

A display screen surface reflection intensity measuring method comprising: acquiring brightness values of a first screen (21) and of a second screen (22) placed in a same environment when displaying, where the first screen (21) and the second screen (22) are identical in observed brightness, a light-shielding object (201) is arranged around and in front of the first screen (21), and the first screen (21) and the second screen (22) are arranged in parallel; and, acquiring the reflection intensity of the screen surfaces in the environment on the basis of the brightness values of the first screen (21) and of the second screen (22) when displaying. This scheme allows for convenient and accurate measurement of the reflection intensity of the screen surfaces.

Description

technical field [0001] The invention relates to the technical field of visual measurement, in particular to a method and a measuring device for measuring the reflective intensity of a display screen surface. Background technique [0002] The surface of the display of many existing devices is more or less reflective. If the device is used in a relatively bright environment, the surface of the display of the device will reflect ambient light and cause the content displayed on the display to be recognizable. Sexual deterioration. [0003] In this case, it is necessary to know the intensity of ambient light reflected by the display based on visual perception, so as to adjust the brightness of the display according to the reflected light intensity. The current method of measuring brightness generally uses a luminance meter, etc., but the luminance meter cannot directly measure the reflective intensity of the display surface in a bright environment based on visual perception, and...
