Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display screens, in particular to a liquid crystal display screen with increased service life. Background Art

[0002] Liquid crystal display, abbreviated as LCD in English, is a type of flat panel display. It is used for TV and computer screen display. The advantages of this display are low power consumption, small size and low radiation. The liquid crystal display uses a liquid crystal solution in two polarized materials. When the current passes through the liquid, the crystals will be rearranged to achieve the purpose of imaging.

[0003] A conventional liquid crystal display screen is mainly composed of an upper polarizer, an upper glass, a lower glass, a lower polarizer, a driver IC and a metal clip PIN. When the display screen displays abnormally during actual display work, such as display missing, a flowery screen or no display, it is equivalent to the display screen being scrapped, and a new display screen must be replaced. When replacing it again, not only does it require cumbersome disassembly and assembly steps for the display screen, but it also affects the user's demand for timely use of the display screen. Therefore, a liquid crystal display screen with increased service life is proposed. Utility Model Content

[0014] Furthermore, the driver IC 1 is distributed on the top of the side surface of the glass substrate 1, and the metal clip PIN 1 is buckled on the glass substrate 1 and is connected with the corresponding driver IC 1.

[0015] Furthermore, the second lead-out structure includes a second driver IC and a second metal clip PIN.

[0016] Furthermore, the second driver IC is disposed at the bottom of the other side surface of the first glass substrate, and the second metal clip PIN is buckled on the first glass substrate and connected to the corresponding second driver IC.

[0017] Furthermore, the connection between the metal clip PIN 2 and the metal clip PIN 1 and the glass substrate 1 is coated with UV protective glue, which is used to fix the metal clip PIN 2 and the metal clip PIN 1 on the glass substrate 1.

[0034] In order to enable those skilled in the art to better understand the solution of the utility model, 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 only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0035] As mentioned in the background art, if a conventional display screen has display abnormalities during actual display operation, such as display missing, screen distortion or no display, the display screen is scrapped and must be replaced with a new one, which greatly reduces the service life of the display screen.

[0036] In order to solve this technical problem, the utility model provides a liquid crystal display screen with increased service life, which uses a liquid crystal display screen.

[0037] Specifically, please refer to Figure 1-Figure 3 , the LCD screens that increase the service life include:

[0038] A display element 1, wherein a lead-out structure 1 2 and a lead-out structure 2 3 are respectively provided on both sides of the display element 1;

[0039] The display element 1 includes a polarizer 1 11, a glass substrate 1 12, a glass substrate 2 13, a glass substrate 3 14 and a polarizer 2 15;

[0040] Polarizer 1 11, glass substrate 2 13, glass substrate 1 12, glass substrate 3 14 and polarizer 2 15 are laminated from left to right to form a display element 1′.

[0041] Among them, the display element 1 and the lead structure 1 2 together form a display screen 1, and the display element 1 and the lead structure 2 3 together form a display screen 2. When a display screen fails during terminal application, it can be turned off and another display screen can be used for display work.

[0042] The liquid crystal display screen with increased service life provided by the utility model realizes the function of having two independent displays on the liquid crystal display screen through the common design of the display element 1 and the lead-out structure 1 2 and the lead-out structure 2 3. When a certain display screen fails and cannot be used for display, the other display screen can be switched for display, thereby achieving the effect of extending the overall service life of the display screen. In actual use, there is no need to disassemble and replace the display screen through cumbersome steps after the display screen fails, and the use of the display screen function required by the user will not be affected, thereby improving its own practicality.

[0043] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0044] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0045] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0046] Please refer to Figure 1 , Figure 2 and Figure 3 A liquid crystal display screen with increased service life, a display element 1, a lead-out structure 1 2 and a lead-out structure 2 3 are respectively provided on both sides of the display element 1; the display element 1 comprises a polarizer 1 11, a glass substrate 1 12, a glass substrate 2 13, a glass substrate 3 14 and a polarizer 2 15; the polarizer 1 11, the glass substrate 2 13, the glass substrate 1 12, the glass substrate 3 14 and the polarizer 2 15 are sequentially bonded from left to right to form the display element 1 together, wherein the display element 1 and the lead-out structure 1 2 together form a display screen 1, and the display element 1 and the lead-out structure 2 3 together form a display screen 2. When a display screen fails during terminal application, it can be turned off and another display screen can be used for display work.

[0047] Please refer to Figure 2 and Figure 3 , the polarizer 11, the glass substrate 12, the glass substrate 13 and the polarizer 15 in the display element 1 and the lead-out structure 12 together constitute a display screen 1;

[0048] The polarizer 1 11, glass substrate 1 12, glass substrate 3 14 and polarizer 2 15 in the display element 1 and the lead-out structure 2 3 together constitute display screen 2;

[0049] The lead-out structure 2 includes a driver IC 21 and a metal clip PIN 22. The driver IC 21 is distributed on the top of a side of the glass substrate 12. The metal clip PIN 22 is buckled on the glass substrate 12 and corresponds to the driver IC 21.

[0050] The liquid crystal display screen with increased service life provided in this embodiment can be connected to an external PCB board through the metal clip PIN-22 in the lead-out structure-2 during actual application, so that the display screen-1 can be driven by the lead-out structure-2, so that the liquid crystal display screen can display the screen through the display screen-1 during actual application;

[0051] When display screen one cannot display due to display defects, screen noise, etc., the lead structure 2 3 can be used to drive and control the display screen separately, so that display screen two can display, so that the entire LCD screen can still display, meeting the user's display needs. Compared with the traditional LCD screen with only a single display area, the service life of the entire LCD screen is effectively improved, and at the same time, there is no need to replace the damaged screen and it can still be used for normal display.

[0052] The liquid crystal display screen with increased service life provided in Example 1 is further optimized, specifically, as follows: Figure 2 As shown, the lead structure 2 3 includes a driver IC 2 31 and a metal clip PIN 2 32;

[0053] The second driving IC 31 is disposed at the bottom of the other side of the first glass substrate 12 , and the second metal clip PIN 32 is buckled on the first glass substrate 12 and connected to the corresponding second driving IC 31 .

[0054] Through the above structural design, when the display screen 1 is damaged during operation, the display screen 2 can be driven and displayed by the cooperation of the driver IC 2 31 and the metal clip PIN 2 32 with the external structure, thereby realizing the independent display control of the display screen 2, and meeting the functional requirement of the long service life of the liquid crystal display screen;

[0055] The display screen 1 can be controlled and displayed independently through the driving IC 1 21 and the metal clip PIN 1 22 . Similarly, the display screen 2 can be controlled and displayed independently through the driving IC 2 31 and the metal clip PIN 2 32 .

[0056] The liquid crystal display screen with increased service life provided in Example 1 or 2 is further optimized, such as Figure 1-Figure 3 As shown, the connection between the metal clip PIN 2 32 and the metal clip PIN 1 22 and the glass substrate 1 12 is coated with UV protective glue 4 for fixing the metal clip PIN 2 32 and the metal clip PIN 1 22 on the glass substrate 1 12 .

[0057] Compared with traditional display screens, this LCD screen has an additional driver IC interface and a corresponding metal clip PIN. Therefore, it is particularly important to protect the connection between the driver IC and the metal clip. This ensures that when a display screen has a problem, another display screen can achieve independent control display through the corresponding driver IC and metal clip PIN.

[0058] To this end, UV protective glue 4 is provided. Specifically, after the metal clip PIN 2 32 and the metal clip PIN 1 22 are connected to the glass substrate 12, UV protective glue is applied to the surface of the connection, and then ultraviolet rays are irradiated on the glue-coated area to cure the irradiated glue layer to form effective protection for the connection.

[0059] The liquid crystal display screen with increased service life provided in Example 3 is further optimized, such as Figure 1 As shown, the step between the glass substrate 12 and the glass substrate 2 13 is covered with a black glue silica gel 5 for protecting the driver IC 21;

[0060] The step between the glass substrate 1 12 and the glass substrate 3 14 is covered with black glue silica gel 2 6 for protecting the driver IC 2 31;

[0061] The black glue silicone 1 5 and the black glue silicone 2 6 provided in this embodiment are similar to the UV protective glue in embodiment 3, and are both for ensuring the stability of the connection between the driver IC 2 31 and the metal clip PIN 2 32, the driver IC 1 21 and the metal clip PIN 1 22, and the subsequent stable use.

[0062] The liquid crystal display screen with increased service life provided in Example 4 is further optimized, such as Figure 1 As shown, the tails of the metal clip PIN 2 32 and the metal clip PIN 1 22 are extended toward the direction of the glass substrate 1 12 for connecting with the external PCB board, and the two metal clip PIN 2 32 and the metal clip PIN 1 22 are arranged in parallel with each other;

[0063] Through the above structural design, when the LCD screen is connected to an external PCB board, the PCB can be placed in a single direction to connect with two corresponding metal clips PIN 2 32 and metal clip PIN 1 22, thereby effectively reducing the overall module thickness after the LCD screen is assembled with the external structure.

[0064] The use process of the liquid crystal display screen with increased service life provided by the utility model is as follows: the lead-out structure 1 2 and the lead-out structure 2 3 are connected to the corresponding PCB board, so that the lead-out structure 1 2 and the lead-out structure 2 3 can respectively realize the independent display control of the display screen 1 and the display screen 2. Specifically, in the actual application process, the display of the display screen 1 is realized by the independent control of the driver IC 1 21 and the metal clip PIN 1 22, that is, the polarizer 1 11, the glass substrate 1 12, the glass substrate 2 13 and the polarizer 2 15 form a display module to display the display picture;

[0065] When the display screen fails, the display control of the second display screen is immediately and independently realized through the driver IC 2 31 and the metal clip PIN 2 32, that is, the polarizer 1 11, the glass substrate 1 12, the glass substrate 3 14 and the polarizer 2 15 are displayed together;

[0066] Through the above operation, the normal display work of the entire LCD screen can be achieved without replacing the display screen, which effectively increases the service life of the entire LCD screen.
