[0018] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] Figure 1 A schematic diagram of a process flow provided by an embodiment of the present utility model, such as Figure 1As shown, this embodiment provides, including: a display module 1, a photoelectric sensor 2, a main board 3, a front frame 4 and a back cover 5.

[0020] like Figure 1 and Figure 2 As shown, a plurality of photoelectric sensors 2 are respectively attached to the front and back sides of the display module 1. Specifically, it is preferred to attach the photoelectric sensors 2 to the four corners of the front side, the four corners of the back side and the center of the display module 1. In order to make the sensing range of the photoelectric sensors 2 fully cover the LCD display module, the photoelectric sensors 2 attached to the front side of the display module 1 and the photoelectric sensors attached to the back side are arranged alternately. The mainboard 3 is arranged in contact with the photoelectric sensors 2 arranged on the back side of the display module 1.

[0021] The front frame 4 and the rear cover 5 are provided to fix each photoelectric sensor 2 to prevent it from falling. Specifically, the front frame 4 has a notch 6, which matches the position of the photoelectric sensor 2 attached to the front of the display module 1. The front frame 4 is buckled to the front of the display module 1. The notch 6 on the inner surface of the front frame 4 can be completely attached to the photoelectric sensor 2 attached to the front of the display module 1. Preferably, a buffer layer is provided inside the notch 6 to prevent shock. The rear cover 5 matches the front frame 4, and the rear cover 5 is usually buckled and fixed to the front frame 4, thereby fixing the display module 1, the photoelectric sensor 2, and the mainboard 3.

[0022] It should be noted that the display module 1 in the technical solution of the utility model is usually an LCD display module or an LED display module. In actual production, if the display screen of the product is composed of several LCD display modules or LED display modules, each LCD display module or LED display module has the above-mentioned photoelectric sensor arrangement structure.

[0023] Each photoelectric sensor 2 is connected to the mainboard 3 via an I2C pin / SPI pin, thereby constructing a data transmission path. The utility model adopts an ambient light sensor (ALS) based on the Texas Instruments OPT3001 and other models. The mainboard 3 in the utility model is configured with the I2C or SPI interface of the photoelectric sensor 2.

[0024] The technical solution of the utility model is now described in detail in combination with the production process, specifically:

[0025] Mount photoelectric sensors 2 at the four corners of the front of the display module 1, assemble the front frame 4 with the front of the display module 1, and fix the front photoelectric sensor 2 with the display module 1 to prevent position displacement caused by external impact and vibration. Turn the product over and attach the photoelectric sensor 2 to the back of the display module 1 as shown in the figure. After attaching, install the mainboard 3 on the outermost layer so that the photoelectric sensor 2 is connected to the mainboard 3 through the I2C pin / SPI pin to build a data transmission path.

[0026] The utility model arranges each photoelectric sensor 2 at a specific staggered position on the front and back sides of the liquid crystal LCD, so as to transmit information at different positions to the main board 3. Figure 2 In the structure shown, the front frame 4 and the rear frame are buckled together to avoid multiple photoelectric sensors 2.

[0027] In actual use, when the display runs some specific monochrome images, each photoelectric sensor 2 collects brightness on the front and back sides of the LCD display. The staff compares the values ​​of the photoelectric sensors 2 at different positions to find out the local brightness differences when the display is abnormal.

[0028] This display abnormality identification arrangement structure can fully monitor whether the display is abnormal, so as to better meet the safe use in medical scenarios.
