A tunable light-mixing liquid crystal lens-like cell (LCLC) is proposed to limit color shift and improve the viewing angle performance. The LCLC is attached on a collimated display, which is introduced to avoid the blue shift of OLED or phase difference of LCD. At voltage on-state, the incident light with low color shift is mixed by the LCLC to ensure the low color shift at different viewing angles, the brightness is also diffused to large viewing angles. At voltage off-state, the incident light is invariant after it is transmitted the LCLC. Using LCLC, display can meet more complex requirement owing to the tunable property of brightness distribution.

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.
