Embodiments of the present invention provide a storage circuit, a driving chip and a display device. The storage circuit includes a storage module and an enabling module. The enabling module includes a control unit and an enabling unit. The control unit is electrically connected to the enabling unit, and the enabling unit is electrically connected to the storage module. The storage module includes a plurality of idle storage modules, and the idle storage modules are storage modules that do not need to be used. The control unit obtains the first clock signal and the second clock signal. The control unit corresponding to the idle storage module decodes the idle trigger signal according to the first clock signal and the second clock signal, and provides the idle trigger signal to the corresponding enabling unit. The multiple enabling units corresponding to the multiple idle storage modules simultaneously send enable signals to the multiple idle storage modules according to the idle trigger signal. Multiple idle storage modules obtain idle data simultaneously according to the enable signal. It can solve the problem of multi-resolution skipping unused storage modules without additional jumpers.
Description
Technical field [0001] The invention relates to the technical field of digital video processing, in particular to a memory circuit, a driving chip and a display device. technical background [0002] In the current driver chip products, the driver chip needs a lot of compatible resolutions. The driving chip charges the capacitance on the screen in the way of line scanning, so there needs to be a serial-to-parallel memory circuit inside. [0003] The capacity of the memory circuit is designed according to the maximum resolution. If the resolution is smaller than the maximum resolution, some memory cells in the memory circuit will be selected to store data. At present, mainstream chips all choose the memory cells on both sides. For the big data side, the storage unit in the middle is not used and needs to be skipped. In order to realize this function, the jumper is generally used to control the clock or enable signal of the storage unit. If the resolution is large, the method of jum...
