The smaller the △E is, the better the integrated black visual effect is. If it is less than 1, there is a better integrated black visual effect. The brightness, red and green, and yellow and blue values ​​of the display area and the non-display area are collected respectively, and the △E is obtained after the difference calculation, which means that the visual effect of integrated black is a comparative value. Therefore, this solution can automatically change the absorption capacity of the non-display area when the outdoor light changes with the angle of sunlight, thereby achieving a better integrated black viewing effect.

[0062] Furthermore, for outdoor display screens in fixed locations, the angle of natural light exposure is relatively fixed every day over a long period of time (measured in months or quarters). Therefore, the processor can collect the natural light exposure angle only once within the planned cycle based on a monthly or quarterly collection plan, and use a fixed control scheme for each injection component within the cycle, which is beneficial to saving data processing energy consumption and costs.

[0063] Example 2

[0064] This embodiment provides a screen integrated black adjustment method using the screen integrated black adjustment system in Embodiment 1, such as Figure 2 As shown, the following steps are included:

[0065] Step 1: obtaining the illumination direction of natural light relative to the screen at the current moment through the illumination acquisition component;

[0066] Step 2: After receiving the irradiation direction of natural light, the controller in communication with the illumination component sends a control signal to the injection component, wherein the control signal is used to control the injection parameters of the filling ink injected into the bonding block by the injection component;

[0067] Step 3, injecting a filling ink with a first metal oxide concentration into a position of the bonding block corresponding to a direction of natural light irradiation through an injection port, and injecting a filling ink with a second metal oxide concentration into other positions of the bonding block, wherein the first metal oxide concentration is greater than the second metal oxide concentration;

[0068] Step 4: the filling ink after absorbing the red ultraviolet rays in the bonding block flows out from the outflow port of the bonding block, and the heat dissipation component connected to the outflow port receives the filling ink and dissipates the heat of the filling ink.

[0069] Optionally, in this embodiment, the bonding block includes an upper bonding block, a lower bonding block, a left bonding block and a right bonding block, each of which is provided with an injection port and an outflow port to respectively realize the injection and outflow of the filling ink;

[0070] Step three specifically includes:

[0071] When the irradiation direction of natural light is close to the upper part of the screen, filling ink with a first metal oxide concentration is injected into the injection port of the upper bonding block, and filling ink with a second metal oxide concentration is injected into the bonding blocks of other parts; optionally, when the irradiation direction of natural light is close to the upper part of the bonding block, it means that the light intensity of the upper part of the bonding block is stronger than that of other parts. Therefore, the concentration of metal oxide in the filling ink injected into the upper bonding block is greater than the concentration of metal oxide in the filling ink in the other three parts; so as to improve the effect of the upper bonding block in absorbing red ultraviolet rays, reduce the irradiation temperature rise at the position of the upper bonding block, and thus achieve the display effect of the screen being one-piece black.

[0072] When the irradiation direction of natural light is close to the upper left part of the screen, filling ink with a first metal oxide concentration is injected into the injection ports of the upper bonding block and the left bonding block, and filling ink with a second metal oxide concentration is injected into the bonding blocks in other parts. Similarly, when the irradiation direction of natural light is close to the upper left part of the bonding block, it means that the light intensity in the upper left part of the screen is stronger, and correspondingly, filling ink with a higher metal oxide concentration is injected.

[0073] When the irradiation direction of natural light is perpendicular to the surface of the screen, filling ink with a second metal oxide concentration is injected into the injection ports of the upper bonding block, the lower bonding block, the left bonding block and the right bonding block.
