A display device includes a first support plate and a pixel region over the first support plate. A thin film transistor (TFT) structure is disposed over the first support plate and associated with the pixel region. The TFT structure includes a first metal layer over the first support plate. The first metal layer includes a gate. A silicon layer is disposed over the gate. A second metal layer is disposed over the silicon layer.

A voltage driver can be operated to power an electrowetting lens of an eye-implantable or eye-mountable device. The voltage driver includes a first charge pump that outputs a first voltage having a first polarity and a second charge pump that outputs a second voltage having a second polarity, where the second polarity is an opposite polarity of the first polarity. The voltage driver can be operated to charge the electrowetting lens by coupling the first charge pump to the electrowetting lens and, after charging the electrowetting lens, discharge the electrowetting lens by coupling the second charge pump to the electrowetting lens. In operation, charging and discharging the electrowetting lens adjusts an optical power of the electrowetting lens and can thus adjust an optical power available for vision when the electrowetting lens is implanted in or mounted on an eye.

An electrowetting display comprises a support plate on which individual electrowetting pixels separated from one another by pixel walls are formed. The individual electrowetting pixels include an electrode layer on the support plate, and a dielectric barrier layer on the electrode layer. The dielectric barrier layer comprises a first portion having a first dielectric constant and a second portion having a second dielectric constant that is substantially less than first dielectric constant. A hydrophobic layer is on the first portion and the second portion of the dielectric barrier layer.

A transparent display panel is provided, including a liquid crystal cell, a chromic material and a trigger component. The liquid crystal cell includes an array substrate and a first transparent substrate disposed opposite each other. A liquid crystal layer is arranged between the array substrate and the first transparent substrate. The chromic material is arranged at a side of the first transparent substrate away from the array substrate. The trigger component is connected to the chromic material for enabling the chromic material to perform a reversible change between a transparent state and a colored state.

An electrowetting display device includes light steering structures that direct incoming light away from pixel walls. According to some configurations, transparent or semi-transparent pixel walls are shielded from incoming light by a black matrix (BM) material in a color filter plate and by the light steering structures. Instead of the incoming light being completely blocked by the black matrix, at least a portion of the incoming light that would have been blocked by the black matrix is directed by one or more of the light steering structures to an area of the pixel such that the brightness of the pixel is increased.

A method of dispensing fluids for manufacturing an electrowetting element. The method comprises: dispensing a first layer of a first fluid on a support plate surface; letting a first portion of the first fluid vaporize as a vapor from the first layer into a region over the first layer; removing the vapor from the region over the first layer; and dispensing on the first layer a second layer of a second fluid, the second fluid immiscible with the first fluid.

A display device includes a first support plate and a second support plate. A pixel region between the first support plate and the second support plate includes a plurality of pixel wall portions over the first support plate forming a perimeter of the pixel region. A first liquid and a second liquid that is immiscible with the first liquid are disposed in the pixel region. A light-blocking portion is disposed on an inner surface of the second support plate and over a first pixel wall portion of the plurality of pixel wall portions. A recessed region is aligned with the light-blocking portion. An electrically conductive layer is disposed within the recessed region and disposed on a portion of the light-blocking portion. The electrically conductive layer has a first surface contacting the second liquid.

A display device includes a first support plate and an opposing second support plate. A pixel region is positioned between the first support plate and the second support plate. A thin film transistor (TFT) structure is formed on the first support plate and associated with the pixel region. The TFT structure includes a source and drain electrode layer. A reflective layer is formed or disposed over the source and drain electrode layer. The reflective layer includes a pixel electrode within the pixel region. A via is between the source and drain electrode layer and the reflective layer to electrically couple the pixel electrode to the source and drain electrode layer. An organic layer is formed or disposed over the via. The organic layer includes an elevated surface over the via.
