Technical Field

[0002] A curved TV refers to a TV with a screen that has a certain curvature and a certain curved shape. Curved TV is a technological masterpiece based on advanced technologies such as the use of flexible screens that are thinner than flat-screen TVs. Its curvature is generally consistent with the curvature of the human eyeball, which is more in line with the design of the human eye. It can bring a more comfortable feeling to the human eye and has the characteristics of excellent contrast, a wide viewing angle, etc.

[0003] At present, when curved TVs are produced, the flat structure of the LCD panel is deformed during the bending process. The edge area is supported by fixings such as frame glue, so the deformation of the isolation parts in this area is small. The middle area of ​​the panel is not supported by fixings such as frame glue, so it will be subjected to greater stress when bending, resulting in a greater compression deformation of the isolation parts in the middle area than the isolation parts in the edge area. The light-transmitting medium between the liquid crystal substrates needs to ensure the stability of the curved liquid crystal. At the same time, when the curved liquid crystal substrate is squeezed, the light-transmitting medium inside it plays a certain compressive resistance role, and the light-transmitting medium needs to ensure the tightness and integrity of the filling. Therefore, in the process of lens medium injection, it is necessary to ensure the stable injection of the light-transmitting medium.

[0046] Embodiment 1

[0047] See also Figure 1 As shown, the present invention is a pressure-resistant curved surface liquid crystal television, and the preparation method of the liquid crystal television comprises the following steps:

[0048] Step 1: Substrate production: Use high-precision silicon wafers to produce liquid crystal substrates, and then apply a light-transmitting medium between the liquid crystal substrates to form a liquid crystal base layer;

[0049] Step 2: Liquid crystal layer preparation: filling the liquid crystal medium between the light-transmitting medium to form a liquid crystal layer;

[0052] Embodiment 2

[0053] Reference Figure 2 As shown, based on the injection process of the light-transmitting medium in the liquid crystal layer, this embodiment provides the following technical solutions:

[0054] Step A1: aligning and fixing two liquid crystal substrates coated with liquid crystal base layers; obtaining assembly information of the liquid crystal substrates, including a length value C of the liquid crystal substrates and a liquid cavity width value K of the liquid crystal substrates;

[0055] pass The liquid cavity deviation value Bp of the two liquid crystal substrates is calculated; wherein K0 is the standard value of the liquid cavity of the liquid crystal substrate;

[0056] Determine whether the liquid cavity deviation value Bp is within the deviation value range [Bpin, Bpax];

[0057] If the liquid cavity deviation value Bp is within the deviation value range [Bpin, Bpax], a liquid injection signal is generated;

[0058] If the liquid cavity deviation value Bp is within the deviation value range [Bpin, Bpax], a deviation signal is generated;

[0059] Step A2: based on the injection signal, calibrate the injection device, adjust the temperature of the liquid crystal transparent medium to meet the temperature threshold range standard, and inject the transparent liquid crystal transparent medium between the two liquid crystal substrates;

[0060] Acquire injection data within the injection time T, the injection data including injection flow rate ZYv and injection pressure ZYy;

[0061] Based on the injection data and the assembly information of the liquid crystal substrate, the liquid level height approval value YHJ of the light-transmitting medium at the injection time T is calculated by the injection influence model; and then the liquid level height approval value range [YHJin, YHJax] is obtained;

[0062] It should be noted that the approved value of the liquid level YHJ is the theoretical calculated value of the liquid level at the injection time T obtained by theoretical calculation based on the assembly information of the liquid crystal substrate and the injection data during the injection process of the light-transmitting medium, and the approved value range of the liquid level [YHJin, YHJax] refers to the error range of the approved value of the liquid level YHJ, wherein, , , YHJc is the maximum liquid level height deviation;

[0063] Step A3: Obtain the liquid level of the light-transmitting medium in the liquid crystal substrate at the injection time T, and mark it as YH T ;

[0064] Determine the liquid level YH of the light-transmitting medium T Whether the liquid level is within the approved value range [YHJin, YHJax];

[0065] If the liquid level of the transparent medium is YH T If the liquid level is within the approved value range [YHJin, YHJax], a stable injection signal is generated; at this time, the injection speed ZYs and the injection pressure ZYy are maintained to continue the injection;

[0066] If the liquid level of the transparent medium is YH T If the liquid level is not within the approved value range [YHJin, YHJax], an abnormal injection signal is generated; at this time, it indicates that the injection pressure ZYy is abnormal; the injection pressure ZYy needs to be analyzed and regulated;

[0067] Step A4: Determine the light-transmitting medium liquid level YH T Compare with the minimum approved liquid level height YHJin and the maximum approved liquid level height YHJax;

[0068] If the liquid level of the transparent medium is YH T is less than the minimum approved liquid level value YHJin; an overpressure signal is generated, which indicates that the injection pressure on the light-transmitting medium during the injection process is too high, resulting in a low liquid level in the light-transmitting medium; at this time, it is necessary to monitor the state of the liquid crystal substrate and adjust the injection pressure; then, execute step A5;

[0069] If the liquid level of the transparent medium is YH Tis greater than the maximum approved liquid level YHJax; a low pressure signal is generated, which indicates that the injection pressure of the light-transmitting medium during the injection process is relatively low, resulting in the presence of gas in the light-transmitting medium, which causes the liquid level of the light-transmitting medium to be relatively high; then, step A6 is executed;

[0070] Step A5: Obtain the liquid cavity injection width value K of the liquid crystal substrate at the injection time T T , and the liquid cavity filling width value K T Compare with the liquid cavity width value K;

[0071] If the liquid cavity filling width value K T If it is greater than the liquid cavity width value K, an assembly curing signal is generated; that is, it means that the two liquid crystal substrates did not meet the fixing standard during alignment and fixing, resulting in the liquid crystal substrate being cheap during the injection process;

[0072] If the liquid cavity filling width value K T is equal to the liquid cavity width value K, then a pressure reduction signal is generated, which means that during the liquid injection process, the alignment and fixation of the two liquid crystal substrates meet the standard, but during the liquid injection process, the liquid injection pressure is too large, resulting in a decrease in the gap between the light-transmitting media, and then causing the liquid level to drop; at this time, based on the liquid injection influence model, the liquid injection pressure reduction value ZYj is calculated to reduce the liquid injection pressure;

[0073] Step A6: Based on the injection impact model, calculate and obtain the injection pressure increase value ZYs, and increase the injection pressure.

[0074] By monitoring the injection state of the light-transmitting medium between the liquid crystal substrates, and based on the information of the injection pressure and the injection time, it is calculated and judged whether there is any abnormality in the injection process of the light-transmitting medium. When the injection of the light-transmitting medium is abnormal, the injection conditions are adjusted based on the information such as the state of the light-transmitting medium and the injection pressure, so that during the injection process, the light-transmitting medium can achieve a compact filling effect between the two liquid crystal substrate coatings, effectively ensuring the stability of the injection of the light-transmitting medium between the liquid crystal substrates, and at the same time, it can improve the compressive strength between the two liquid crystal substrates, avoiding the problem of the light-transmitting medium being unable to transmit light due to extrusion. By monitoring the injection process of the light-transmitting medium, mixed gas in the light-transmitting medium during the injection process is avoided, and the qualified rate of the light-transmitting medium injection is guaranteed, thereby ensuring the qualified rate of the liquid crystal production.
