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 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 discloses a display panel, a display device and a driving method. The display panel includes a substrate, a sub-pixel array and a plurality of data lines; when the plurality of data lines input a first voltage data signal and a second voltage data signal to a plurality of sub-pixels in the sub-pixel array, the input signal of the first voltage data signal The sub-pixels and the sub-pixels to which the second voltage data signal is input are alternately arranged, and in a plurality of sub-pixels of the same color in the same row, the sub-pixels to which the first voltage data signal of positive polarity is input and the first voltage data signal of negative polarity are input The number of sub-pixels is the same. The display panel can improve the large viewing angle deviation problem of the large-sized display panel, and at the same time, it can also avoid the color deviation of the output image of the display panel, and improve the output image quality of the display panel.

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.
