“…However, it needs a pretty high voltage. In order to lower the applied voltage, modified IPS structures, for example, alternate electrodes [6], wall-shaped electrodes [7], protrusion electrodes [8], and corrugated electrodes have been proposed. From the perspective of manufacturing technology, the electrode shape of these structures is nonplanar and difficult to realize.…”

We propose a transmissive double-side in-plane-switching (IPS) electrodes blue-phase liquid crystal display (LCD) with permittivity protrusion. The potential drops very slowly in the permittivity protrusions, thus the field penetrating depth is significantly enlarged and the operating voltage is lowered. This device has the advantages of fast response time, easy manufacturing process, and low operation voltage.

“…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.
