“…Wide-view transflective blue-phase liquid crystal displays (TRBP-LCDs) are promising for mobile applications on account of their good sunlight readability. 21 In the T region, the backlight passes through the LC layer once, while in the R region, the ambient light traverses the LC layer twice. To achieve the same phase retardation for the T and R regions, several TRBP-LCDs have been proposed, such as a TRBP-LCD using an etched IPS structure, 22 a TRBP-LCD using opposite polar electrodes with etched depth of the glass substrate in the T region, 23 and a TRBP-LCD using alternating structure between polar opposite electrodes and common electrodes.…”

A transflective blue‐phase liquid crystal display (TRBP‐LCD) based on fringe in‐plane switching (FIS) electrodes is proposed. The proposed structure generates combined fringe and in‐plane electric fields that cause more liquid crystal (LC) molecules to reorient almost in plane above and between the pixel electrodes. The fringe field is mainly generated in the transmissive (T) region, and the horizontal electric field is mainly generated in the reflective (R) region. By optimizing the width of the pixel electrodes and the gap between two adjacent pixel electrodes, the different electric field intensity in the T and R regions contribute to balance the optical phase retardation between the T and R regions. As a result, the proposed TRBP‐LCD exhibits a low operating voltage and high optical efficiency, while it preserves a relatively simple fabrication process.

“…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.…”
