39results about How to "Avoid color deviation" patented technology

The method and apparatus use two inequalities to determine whether an estimated value obtained from conventional method and a correct value obtained from ideal conversion is identical. When those values are the same, the estimated value is not corrected; otherwise, according to the difference between those values, one is added or subtracted from the estimated value to obtain the correct result.

The invention provides an OLED display panel. The OLED display panel comprises a plurality of sub-pixels arranged in an array, a plurality of scanning signal lines, a plurality of light-emitting signal lines, a plurality of first driving voltage lines, a plurality of data signal lines, at least one second driving voltage line and at least one third driving voltage line, wherein the scanning signallines, the light-emitting signal lines and the first driving voltage lines extend in the horizontal direction, and the data signal lines, the second driving voltage lines and the third driving voltage lines extend in the vertical direction, wherein each scanning signal line is connected with a row of sub-pixels, each light-emitting signal line is connected with a row of sub-pixels, each first driving voltage line is connected with a row of sub-pixels, and each data signal line is connected with a column of sub-pixels; the first driving voltage line corresponding to each row of sub-pixels is connected with the second driving voltage line through a first thin film transistor; and the first driving voltage line corresponding to each row of sub-pixels is connected with the third driving voltage line through a second thin film transistor, so that brightness deviation or color deviation of the sub-pixels during light emitting can be avoided.

The emission intensity of a laser beam source, at a time when a laser beam emitted from the laser beam source and scanned by an optical scanning device becomes incident to a laser beam detector provided in a predetermined position on the scanning path of the laser beam in order to hold a position of an electrostatic latent image formed on a photoreceptor constant in the main scanning direction, while at the same time, changing the emission intensity of the laser beam, is set so as to become the consistently same emission intensity regardless of a change in emission intensity at the time of electrostatic latent image formation onto a photoreceptor. This allows the detection timing of a laser beam by a laser beam detector to be kept constant.

A light emitting diode includes a base, a light emitting chip, and a wavelength converting layer. The base is formed with a recessed portion that has a bottom wall surface, and a side wall surface extending upwardly from the bottom wall surface and cooperating with the bottom wall surface to define a receiving space. The light emitting chip is provided on the bottom wall surface of the receiving space, and has a top chip surface disposed below a top surface of the base, and a peripheral chip surface extending downwardly from the top chip surface and being substantially parallel to and forming a gap with the side wall surface of the recessed portion. The wavelength converting layer is filled in the receiving space in the recessed portion so as to cover the top chip surface and the peripheral chip surface of the light emitting chip.

The invention provides a display panel and a manufacturing method thereof. The method includes the following steps: providing a light-transmitting substrate of which one surface is provided with a semi-light-transmitting reflective layer thereon; the surface of the semi-light-transmitting reflective layer of the light-transmitting substrate forming a reflective plate, such that the surface that faces towards the semi-light-transmitting reflective layer of the reflective plate is parallel to a reflective surface of the light-transmitting substrate, forming a movable reflective unit in the reflective plate, the surface of the reflective plate that faces towards the semi-light-transmitting reflective layer acting as the reflective surface of the reflective plate. The method guarantees that the light-transmitting substrate and the reflective plate are parallel in corresponding parts, realizes substantially flattened interface surfaces, obviates the need for the limit on height differences in distances of the two interface planes by absolute flatness, thus preventing deflection of color display and increasing imaging quality.

Disclosed is a direct type reflective sheet structure, comprising a reflective sheet, on which a plurality of light emitting diode light sources are arranged in an array. A plurality of triangular prism-shaped microstructures is arranged at intervals on the reflective sheet around each of the light emitting diode light sources. Each of the microstructures has a reflective surface facing the light emitting diode light source to reflect light emitted by the light emitting diode light source. Further disclosed is a direct type backlight module. By implementing the embodiment of the present invention, it can avoid the appearance of color deviation on the display panel and reduce the loss of light.
