Abstract: In the technical field of display, a color filter substrate and a curved display device, which can solve the technical problem of low aperture ratio of the existing curved display device, are provided. The color substrate comprises a plurality of sub pixel regions arranged as an array, and black matrixes for separating the sub pixel regions from each other. Measured along a transverse direction, the transverse width of each of all or some of the black matrixes located in the regions at both sides of the color filter substrate is smaller than that of each of the black matrixes located in the region at the center of the color filter substrate. The present disclosure can be applied to curved display device, such as liquid crystal television and curved liquid crystal display device.

Abstract: A light emitting diode (LED) dimming drive device, an LED dimming drive method and a liquid crystal display (LCD) are disclosed. The LED dimming drive device comprises a plurality of dimming control circuits each comprising one dimmer switch and a delay setting circuit for setting a different delay time for each dimming control circuits. Each of the dimming control circuits further comprises a clock delay circuit for receiving a pulse width modulation (PWM) signal, timing according to the delay time, and outputting the PWM signal to the dimmer switch when the delay time expires. Different delay times can be used to control the output of PWM signals and further control the on or off of the dimmer switches. This can avoid the noises or electromagnetic (EM) interferences occurred by a large amount of energy transmitted into the LED paths when the dimmer switches is turned on.
