“…In order to cope with different application environments, some multi-functional LC such as switchable LC lens between positive and negative [16][17][18], rotatable LC lenses [19][20][21][22], LC lenses with switchable optical aperture [18,24], polarizer-free and fast response LC lens used blue liquid crystal (BPLC) [25][26][27][28][29][30][31] have been proposed. Among them, a rotatable LC lens is particularly promising because it can achieve the image switchable function for landscape and portrait, which is very important for handheld electronic equipments such as tablet computers or mobile phones.…”

A liquid crystal (LC) lens array with a half‐wave plate (HWP) to enable the function of switchable lens array between 1 dimensional (1D) and 2 dimensional (2D) arrays is proposed in this paper. The LC cell contains two LC layers which can be driven independently. Through controlling these two LC layers, three different modes of the LC cell such as a lensless system, rotatable 1D lens array and 2D lens array can be switched freely. These three different modes are used for coexistence of 2D and 3D displays, a narrow 3D display viewing angle for a single viewer in an energy‐saving method and a wide 3D display viewing angle for more viewer. Therefore, we propose a multi‐functional LC lens array in order to meet different application conditions.

“…This is a basic operation principle, which can be utilized to realize LC lenses with GRIN profile through quite a number of approaches. For example, LC lens is driven by patterned electrodes, [15][16][17][18][19][20] LC lens is fabricated through convex or concave surfaces treatment, [21][22][23] and composited dielectric layer is coated on the substrate of LC lens. [24][25][26] Specifically, an important class of LC lenses that offer control of the optical phase profile is based on multielectrode designs.…”

A liquid crystal (LC) lenticular lens array based on fringe field effect is proposed. The gradient refractive index (GRIN) profile can be generated in the LC layer because of the fringe field between the strip-shaped electrodes and the bottom electrode. The proposed LC lenticular lens array possesses ideal lenslike phase profile and shortest focal length (1.199 mm) when the driving voltage is 5.4 V. The focal length can be tuned with millisecond response time by changing the driving voltage of the proposed LC lenticular lens array. The rise time τ rise and decay time τ decay of the proposed LC lenticular lens array are 162 and 94 ms, respectively.
