“…Color-filter-free devices include the field sequential color display (FSCD) and color separation display. FSCDs synthesize full color images by rapidly displaying red, green and blue field images in chronological order [77]. In theory, without filters, FSCD can display three times the screen resolution and light transmission efficiency with a wider color gamut at a lower energy and material cost [78].…”

As consumers pursue higher display quality, Mini-LED backlight technology has become the focus of research in the current display field. With its size advantage (100–200 μm), it can achieve one-thousand-level divisional dimming, and it can also be combined with quantum dot technology to greatly improve the contrast, color gamut, dark state and other element of the display performance of LCD displays. Mini-LED backlight technology is undoubtedly the most ideal solution to realize a highly dynamic range display of LCD displays, and has been widely commercialized in many fields such as TVs, tablet computers, notebook computers, and car monitors. This review mainly introduces the efforts made by researchers to eliminate the halo effect, thinning of the backlight module and reducing the backlight power consumption. The application of quantum dot technology in backlight is also presented. We predict that the number of Mini-LED backlight partitions is expected to reach a level of more than 3000 in the future, further utilizing the advantages of the small size in local dimming, but it will also inevitably be challenged by some issues such as power consumption and heat dissipation.

“…Transparent displays are receiving considerable attention because they can be harmonized naturally without seeming disconnected from the surroundings and can be used anywhere where glass windows are installed [ 1 , 2 , 3 , 4 ]. Unlike conventional displays, such as smart phones, tablets and TV, information can be displayed on a simple transparent glass, which is used as a useful function in windows, head-up displays and even buildings [ 5 , 6 , 7 ].…”

Transparent organic light emitting diode (OLED) display is one of the most promising devices among next-generation information displays because of beneficial characteristics, such as self-emissive and optically clear properties. Nevertheless, in conventional transparent OLED display devices, there are serious intrinsic problems in terms of the transmittance in the dark state because of empty windows in the cell, so the contrast ratio of the transparent OLED display would be deteriorated even though it can exhibit excellent bright state. In general, the transparent mode using the OLED device applies an empty area in each pixel because an emitting device could never reveal the background image, so the transparent OLED should contain the empty area in the pixel for transparent images. This may cause the optical degradation in the dark state. To solve this problem, we propose hybrid-type transparent OLED display modes that apply a liquid crystal (LC) to the transparent window part of the empty space. In this paper, we applied two dichroic LC modes— which use an electrically controlled birefringence (ECB) mode (Heilmeier type) for the polarized mode and a cholesteric LC mode (Guest-Host mode) for the non-polarized mode—to the empty area. In each hybrid mode, we have observed optical performance, including the transmittance in the dark/bright state, contrast ratio and response time as a function of cell parameters. As a result, we confirmed that the dark state and the contrast ratio could be improved by applying the proposed modes without serious decay of the transmittance in the bright state.

Through a series of diffracted see-through images of transparent displays, "multiscale structural similarity" is demonstrated to be the most adapted for quality assessment among several mainstream algorithms. Then aperture ratios, resolutions, and pixel geometries are evaluated and revealed to affect see-through image quality from the most significantly to the least.
