Claims

[Scope of utility model registration request]

A CRT, a pattern memory that stores the dot number pattern displayed on the CRT, a read register into which a single dot pattern is loaded from the pattern memory, and a dot signal connected to this register and sent from the register are independent. and an independent point emphasizing circuit that detects whether the dot signal is a display dot signal that is displayed independently and outputs an emphasized display dot signal to the CRT when the display dot signal is an independently displayed display dot signal. The circuit includes a 3-bit shift register that receives the dot signal sent from the readout register that receives the dot signal, and a signal output from each bit of this shift register, and emphasizes when only the center bit is the display dot signal. A CR7 display device comprising: a Kent circuit that outputs a display dot signal.
