[0036] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0037] First, refer to Figure 1 , an embodiment of the present invention provides a method for quantifying yellowing of a display screen, comprising:

[0038] S10, setting the display screen to a test environment and performing a squeeze test;

[0039] S20, obtaining and saving the yellowing triggering force of multiple sides of the display screen;

[0040] S30, comparing whether the yellowing triggering force of the display screen exceeds a preset squeezing force range.

[0041] Among them, refer to Figure 2 , the step S10 of setting the display screen to a test environment and performing a squeeze test includes:

[0042] S11, lighting up the screen of the display screen, and making the screen of the display screen present a white picture;

[0043] The test environment is to light up the screen of the display so that the screen presents a white picture. When the display presents a white picture, it is easier to see the yellowing of the display, thereby improving the accuracy of the test.

[0044] S12, placing the display screen under the squeezing device to perform a squeezing test.

[0045] The extrusion test is that an extrusion device squeezes the side of the display screen downward until yellow spots or yellow spots appear on the white screen of the display screen. The extrusion device is a device with an extrusion head that can press down toward the surface of the display screen. The extrusion device slowly squeezes the side of the display screen downward, and stops the downward pressure of the extrusion head by continuously increasing the downward pressure of the extrusion head until yellow spots or yellow spots appear on the white screen of the display screen, and records the extrusion force of the extrusion head at this time. The extrusion force is the extrusion force that triggers yellowing on the side of the display screen. In this embodiment, the side of the display screen is squeezed to perform an extrusion test on the display screen because squeezing the side of the display screen is more likely to cause the undesirable phenomenon of yellowing due to squeezing than squeezing the middle of the display screen, thereby making the test result more accurate.

[0046] Preferably, refer to Figure 3 The step S20 of obtaining and saving the yellowing triggering forces of multiple sides of the display screen includes:

[0047] S21, the squeezing device sequentially squeezes the four sides of the display screen downwards;

[0048] The display screen has four sides. The extrusion forces of the four sides of the display screen caused by the extrusion device to cause yellowing are different, so it is necessary to perform an extrusion test on each side of the display screen. The extrusion device sequentially squeezes downwards the positions close to the four sides of the display screen when the display screen is placed upward, so as to perform an extrusion test on each side of the display screen.

[0049] S22, obtaining four squeezing forces of the squeezing device and generating yellowing triggering forces of four sides of the display screen.

[0050] The squeezing device squeezes the sides of the display screen until yellowing occurs to obtain the squeezing force of the sides of the display screen, and the squeezing force of the sides of the display screen is the yellowing trigger force of the sides of the display screen. The greater the yellowing trigger force, the better the anti-squeezing effect of the display screen is, and the less likely it is to cause yellowing due to squeezing when the display screen is assembled into a complete machine, including in the future use by customers.

[0051] Preferably, refer to Figure 4 , step S30 of comparing whether the yellowing triggering force of the display screen exceeds a preset squeezing force range includes:

[0052] S31, comparing the yellowing triggering forces of the four sides of the display screen with the preset squeezing range in turn;

[0053] The preset extrusion range is the yellowing trigger force range value obtained by performing an extrusion test on several assembled whole machines that have not turned yellow under long-term use.

[0054] S32, screening out display screens whose yellowing trigger force on any side exceeds a preset squeezing range, and judging them as defective.
