“…However, due to light leakage, contrast ratio (CR) of an LCD cannot reach very high, which has been challenged by organic light‐emitting diode (LED) 1 . In order to achieve high CR of the LCDs, many new technologies are developed, such as compensation film design, 2 transflective LCDs, 3,4 and dual‐layer LCDs. By bonding two LC panels with highly transparent optical adhesive, a dual‐layer LCD can effectively reduce light leakage and improve CR 5,6 .…”

The effect of temperature on optical performance of a dual‐layer liquid crystal display (LCD) is investigated by considering LC material parameter and structural deformation of LC panels simultaneously. First, the optical anisotropy of LC material under the influence of temperature is calculated theoretically. Then, the thermal deformations of the dual‐layer LC panels caused by temperature are simulated. Combined with the two factors, the change in optical performance of a dual‐layer LCD under the influence of temperature can be analyzed. In white state, the color in the central area of a dual‐layer LCD is shifted towards blue, and a yellowish border in the edge area may appear. In gray or black state, there may be a light leakage in the edge area of a dual‐layer LCD under the influence of temperature.

“…Transflective liquid crystal displays (TR‐LCDs) have been widely used in mobile devices such as electronic book, tablet personal computers, and cell phones because of their good sunlight readability, as well as low power consumption . A commonly introduced TR‐LCD consists of transmittance (T) and reflectance (R) subpixels, and in the T mode the light is produced by a backlight while R mode uses ambient light to readout the displayed images .…”

“…Transflective liquid crystal displays (TR-LCDs) have been widely used in mobile devices such as electronic book, tablet personal computers, and cell phones because of their good sunlight readability, as well as low power consumption. [1][2][3][4][5][6][7][8][9][10] A commonly introduced TR-LCD consists of transmittance (T) and reflectance (R) subpixels, and in the T mode the light is produced by a backlight while R mode uses ambient light to readout the displayed images. 2 A major technical challenge of the TR-LCDs is to compensate the optical path length between the T and R regions, because the light passes only once through the LC layer in the T subpixel but twice through the LC layer in the R subpixel.…”

A single‐cell‐gap transflective liquid crystal display with a nonuniform electric potential is demonstrated. The top substrate has a top planar common electrode, a transparent dielectric layer with a general dielectric constant is coated on the bottom substrate, and two planar pixel electrodes with the same size are coated on the dielectric layer and the bottom substrate, respectively. With the different gaps between the two planar pixel electrodes and top planar pixel electrode, the nonuniform electric potential from the transmissive region (T region) to the reflective region (R region) is generated, while a bumpy reflector is coated under the bottom substrate. In this device, with the dielectric layer, the pixel and common electrodes generate a strong electric potential in the T region and a relatively weak electric potential in the R region. Consequently, the T and R regions accumulate the same optical phase retardation. The simulation results show that the display exhibits reasonably low operating voltage, high optical efficiency, and well‐matched voltage‐dependent transmittance and reflectance curves. Besides, the fabrication process and the driving mode of the transflective liquid crystal display are relatively simple, and it is suitable for mobile applications.

“…In order to reduce the operating voltage of the BPLC display, two mainstream methods have been explored: (1) optimizing the electrode structure, (2) using a liquid crystal material with a large Kerr constant. Recently, some electrode structures have been proposed, such as alternate electrodes are composed of right triangle electrodes and slanted electrodes [4], partitioned wall-shaped electrodes [5], etc. These special electrode structures all generate a strong horizontal electric field.…”
