Abstract: A bend limiting device includes a flexible support film and limiting chains. The limiting chains are disposed on the flexible support film. Each of the limiting chains includes limiting blocks. Each of the limiting blocks includes limiting structures. One of the limiting structures of one of the limiting blocks is connected to one of the limiting structures of another one of the limiting blocks. When the bend limiting device is bent, two connected limiting structures of two adjacent limiting blocks limit a minimum value of an included angle formed between the two adjacent limiting blocks, so a radius of curvature of each of the limiting chains is limited to be greater than a preset value without being excessively bent. The bent limiting device protects a flexible display panel of a flexible display device from being improperly bent, so as to extend a lifespan of the flexible display device.

Abstract: According to the data driver and the display device provided in the present application, the control module obtains the frequency value of image data according to the image data and outputs the control signal from the plurality of first output terminals according to the frequency value so that the recovery module recovers the clock signal corresponding to the image data under control of the control signal. By outputting the clock signal having corresponding data rate through the frequency value of the image data, an adaptive data rate function can be realized, and a wider data rate range can be realized.
