Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display, in particular to an AMOLED display module with improved strength. Background Art

[0002] OLEDs can be classified into two categories according to the driving method: passive matrix OLED (PMOLED) and active matrix OLED (AMOLED). Among them, PMOLED has high power consumption, which hinders its application in large-size display devices. Therefore, PMOLED is usually used as a small-size display device. AMOLED, due to its high luminous efficiency, is usually used as a high-definition large-size display device. The AMOLED screen is an active matrix organic light-emitting diode panel, which refers to a screen mainly made of AMOLED materials. AMOLED is an active matrix organic light-emitting diode panel. AMOLED screens are widely used in various consumer electronic products such as smartphones, tablets, and TVs.

[0003] AMOLED is an advanced display screen technology with advantages such as excellent color performance, high contrast, ultra-thin design, and flexible display. Compared with traditional liquid crystal panels, AMOLED has characteristics such as faster response speed, higher contrast, and wider viewing angle. AMOLED screens can cover a wider color gamut, presenting more vivid and real colors. At the same time, when displaying dark content, they have higher contrast and deeper black performance. In addition, since there is no need for a backlight and color filters, AMOLED screens can achieve a thinner design, which makes them widely used in thin and light electronic products such as smartphones. AMOLED screens also have good flexibility and can be made into new display forms such as curved screens or folding screens, providing more possibilities for future electronic product design.

[0004] AMOLED is a self-luminous display module with a glass structure and does not require an additional backlight unit. While the TFT module has a backlight unit, and the support structure of the backlight rubber frame or iron frame can greatly improve the overall strength of the module.

[0005] Therefore, the overall strength of the AM display module is not as high as that of the TFT module, and there is a risk of glass structure cracking during the production, transportation, and installation of the client. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an AMOLED display module with improved strength in view of the defects of the prior art.
