Abstract:
1. An apparatus for programming functions of a display, comprising: a memory for storing a program code; a programming device coupled to the memory, the programming device reads the program code with a predetermined length from the memory, wherein the program code with the predetermined length is part of the program code; and a program code checking unit coupled to the programming device, for generating a control signal by checking whether the program code with the predetermined length is consistent with a predetermined state, wherein the predetermined state is that each bit of the program code with the predetermined length is logical “1”, and when the program code with the predetermined length is consistent with the predetermined state, the control signal controls the programming device not to write the program code with the predetermined length into the memory of the display; wherein when the program code with the predetermined length is consistent with the predetermined state, and the logical value of each bit of the memory of the display corresponding to the program code with the predetermined length does not need to be changed.
