Liquid crystal display
View Patent ↗A liquid crystal display includes a gate driver including stages, and a clock generator which receives a clock generation control signal, generates a clock signal and a clock bar signal based on one or more of the clock generation control signal, a gate-on voltage and a gate-off voltage, and outputs the clock signal and the clock bar signal to the gate driver. The clock generator includes an overcurrent protector unit which intercepts at least one of the clock signal and the clock bar signal when a voltage level of at least one of the gate-on voltage and the gate-off voltage is greater than a reference level.
1. A liquid crystal display comprising:
a gate driver including stages; and
a clock generator which receives a clock generation control signal, a gate-on voltage and a gate-off voltage, generates a first clock signal and a second clock signal having a different phase from the first clock signal and outputs the first clock signal and the second clock signal to the gate driver,
wherein
the clock generator includes an overcurrent protector part which intercepts the first clock signal and the second clock signal when a voltage level of at least one of the gate-on voltage and the gate-off voltage is greater than a reference level.
2. The liquid crystal display of claim 1 , wherein the overcurrent protector part generates the reference level, compares the voltage level of the one of the gate-on voltage and the gate-off voltage with the reference level, and intercepts the one of the first clock signal and the second clock signal based on a result of the comparison.
3. The liquid crystal display of claim 1 , wherein the overcurrent protector part comprises:
a first overcurrent protector unit which compares the voltage level of the gate-on voltage with the reference level, and intercepts the first clock signal and the second clock signal based on a result of the comparison; and
a second overcurrent protector unit which compares the voltage level of the gate-off voltage with the reference level, and intercepts the first clock signal and the second clock signal based on a result of the comparison.
4. The liquid crystal display of claim 3 , wherein the first overcurrent protector unit is disposed separate from the second overcurrent protector unit.
5. The liquid crystal display of claim 1 , wherein
the clock generator is connected to the gate driver via transmitting lines which supply the first clock signals and the second clock signals to the gate driver,
each of the transmission lines includes a switching element controlled by the overcurrent protector unit, and
the switching element of each of the transmission lines intercepts a transmission of the first clock signal and the second clock signal based on a result of a comparison of the voltage level of the one of the gate-on voltage and the gate-off voltage with the reference level.
6. The liquid crystal display of claim 1 , wherein the second clock signal has an inverse phase of the first clock signal first clock signal.
