The display is driven by a single set of electrodes between which both layers are sandwiched, the two layers being controllable at least partially independently of one another. Another form of the invention uses three different types of particles within a single electrophoretic layer, with the three types of particles being arranged to shutter independently of one another.

Abstract

Methods of applying a pattern and security devices are disclosed. In one arrangement, a receiving member having a layered structure is provided. The layered structure comprises a layer of phase change material. The phase change material is thermally switchable between a plurality of stable states having different refractive indices relative to each other. An embossing member is stamped into the receiving member. The embossing member heats a selected portion of the layer of phase change material via contact with the receiving member during the stamping. The heating thermally switches phase change material in the selected portion and thereby applies a pattern of different refractive indices to the layer of phase change material.

Abstract

Electrophoretic displays with multi-particle electrophoretic media and improved methods for driving such multi-particle electrophoretic media, especially using active matrix backplanes and controllers. The driving methods use faster gate updates with differential gaps between set of gate updates for a given pixel. The methods are generalizable to any electrophoretic display using push-pull waveforms, and are particularly well-suited for newer multi-particle electrophoretic displays capable of producing four or more colors at each pixel. Using such methods, electrophoretic displays will appear less "flashy" than addressing with conventional row-by-row constant-frame-spacing updating.

Abstract

Electrophoretic displays with multi-particle electrophoretic media and improved methods for driving such multi-particle electrophoretic media, especially using active matrix backplanes and controllers. Larger look-up tables are used, which include a plurality of time-shifted waveforms for each color transition. The controller can thus easily cause a phase shift in the color flashes across the display, which ultimate diminishes or removes the perception that the device is "flashing" during an update from a first image to a second image.. The methods are generalizable to any electrophoretic display using waveforms, and are particularly well-suited for newer multi-particle electrophoretic displays capable of producing four or more colors at each pixel.

Abstract

An electrophoretic medium comprises a fluid and first (B), second (Y), third (R) and fourth (W) particles dispersed in the fluid and having differing colors. The first (B) and third (R) particles bear charges of one polarity and the second (Y) and fourth (W) particles bear charges of the opposite polarity, The first particles (B) have a greater zeta potential than the third particles (R), and the second particles (Y) have a greater zeta potential than the fourth particles (W). One of the particles (W) is white, one of the non-white particles (B) is partially light-transmissive, and the remaining two non-white particles are light-reflective. To display the color of a mixture of the first (B) and second (Y) particles at a viewing surface, the medium is driven to display the second particles (Y) at the viewing surface, then a first driving voltage is applied for a first period to drive the second (Y) and fourth (W) particles towards the viewing surface, then a second driving voltage, of opposite polarity to and lower magnitude than, the first voltage, is applied for a second period less than the first period, and finally the applications of the two driving voltages are repeated.

The roller end cap is rotatably disposed on the end part of the roller, and the torsion spring is inside the roller. One end of the torsion spring is connected to the roller, while the other end is connected to the roller end cap. When a relative rotation between the roller and the roller end cap is occurred, the torsion spring is rotated and deformed to form a restoring force. This restoring force can drive the roller to rotate relative to the roller end cap, thereby making the flexible display panel to roll up along the roller.

Abstract

Waveforms for driving an electrophoretic display including a color filter between a viewer and the electrophoretic medium. Because the waveform results in each image update visiting the white state before the final state, the overall gamut is larger in aggregate and more predictable than simply driving the electrophoretic display including a color filter with the waveforms that are used for black and white grayscale displays.

The electro-optic display also includes a display controller circuit in electrical communication with the common electrode and a first transistor associated with the display pixel. The display controller circuit is capable of applying waveforms to the display pixel by applying one or more time-dependent voltages between the common electrode and the first subpixel electrode via the first transistor, where the one or more time-dependent voltages are applied to the first subpixel electrode. The electro-optic display also includes a second transistor in electrical communication with the first subpixel electrode and the second subpixel electrode. A first enable signal activates the second transistor to place the first subpixel electrode and the second subpixel electrode into electrical communication.

A light source module includes a light guide plate including a light entrance surface and a light source adjacent to the light entrance surface. The light source includes a light emitting device to emit a blue light, a first wavelength conversion unit on the light emitting device and a second wavelength conversion unit on the light emitting unit. When the blue light is incident to the first wavelength conversion unit, the blue light is converted into a first light. The first light has a wavelength in a range from 480 nm to 650 nm. When the blue light is incident to the second wavelength conversion unit, the blue light is converted to a second light. The second light has a wavelength different from the wavelength of the first light. The blue light, the first light and the second light combine to produce a white light.
