“…The light leakage of ADS at dark state has been widely studied [4][5][6][7][8], when ADS LCD panel receives some external and internal stress, the light leakage occurs. And the main reason is the combined effect of the phase retardations from the stressed glass and the LC layer.…”

“…[1][2][3]. But, owing to the homogeneous alignment liquid crystal(LC), ADS mode is sensitive to external stress [4][5][6][7] and is easier to occur light leakage at dark state. Thus, the applications of ADS in large size products of which the deformation is inevitable and difficult to control, and the applications of ADS in the products which are designed to be deformed such as curved panel are limited.…”

45‐4: Late‐News Paper: A Novel ADS Display Technology without Light Leakage

et al. 2020

In the field of LCD, Advanced Super Dimension Switch (ADS) technology is widely used due to its outstanding features, such as high transmittance, wide view, and weak color shift. However, the ADS technology still has intractable problems. One of the most difficult problems is the dark state light leakage under mechanical deformation which is inherent in ADS. In this paper, a novel model called Zero Light Leakage ADS (ZLL-ADS) is proposed, which can completely eliminate the dark state light leakage even under deformation. The key point of ZLL-ADS is the introduction of +A plate in ADS panel. The important role of +A is to compensate the phase retardation of liquid crystals to avoid dark state light leakage caused by external stress on ADS panel. By applying ZLL-ADS technology, the product properties of BOE's ADS Pro, especially the quality of the dark picture has been greatly improved, and the advantages of ADS in high transmittance and wide view are still maintained. The compensation principle is explained theoretically and verified by 18.5 inch FHD flat and curved demoes.

“…For conventional transmissive LCD，the backlight is located below the module and the light emitted by LEDs is converted into a uniform surface light source by LGP (Light guide plate) and optical films。Due to the type of products, such as front light and transparent display, there is no backlight, so the light can only enter the display module from the side [1] . LEDs has a certain luminous angle，therefore, uniform side-in light source cannot be obtained directly.…”

P‐4.5: A New Light‐Guiding Structure for Optimizing the Uniformity of Side‐in Display Source

Zhao

Chen

et al. 2021

In this paper, a new light‐guiding structure for light source of side‐in display products is presented. Under the condition of using LED (Light Emitting Diode) as light source and 8mm pitch, using this structure, a uniform side‐in linear plane light source can be obtained within a light‐mixing distance of 5mm, and 75% uniformity can be achieved. The design of this structure is based on the principle of total reflection and the idea of peak‐load shifting, made of PC (Polycarbonate) material. Compared to traditional LGP (light guide plate), using this structure, uniform plane light source can be obtained in a shorter distance. It is especially suitable for products with front light source and transparent display. Besides, it can be bent or profiled to meet the requirements of narrow frame and special‐shaped products.
