Abstract
A liquid crystal display device has stripe-shaped color filters and arranges the driver ICs on the top or the bottom side portion, and on the left or right side portion of the liquid crystal panel such that the liquid crystal display device has a single bank structure. Accordingly, a difference of a signal delay between the adjacent two odd and even data or gate lines is prevented. As a result, the brightness and the resolution are improved.
Claims17
A liquid crystal display device, comprising:
- a liquid crystal panel having a plurality of gate and data lines and a plurality of sub-pixels, wherein the gate lines are arranged in a transverse direction and the data lines are arranged in a longitudinal direction, wherein each sub-pixel is defined by the gate and data lines and corresponds to a stripe-shaped color filter that has one of red, green, blue and white colors, a black matrix arranged among the stripe-shaped color filters;
- a gate driver integrated circuit (IC) connected to the plural gate lines for driving the gate lines, the gate driver IC arranged on a first side portion of the liquid crystal panel;
- and
- a data driver integrated circuit (IC) connected to the plural data lines for driving the data lines, the data driver IC arranged on a second side portion of the liquid crystal panel.
A method of fabricating a liquid crystal display device, comprising:
- forming a plurality of gate and data lines on a first substrate;
- forming a black matrix on a second substrate;
- forming open portions for color filters by patterning the black matrix;
- depositing a resin on the black matrix covering the open portions, wherein the resin has one of red, green, blue and white colors;
- forming color filters in the open portions by photolithography, the color filters having a stripe shape;
- forming a liquid crystal panel by combining the first and second substrates with interposed liquid crystal;
- installing data driver integrated circuits (ICs) on one side portion of the liquid crystal panel, wherein the data driver ICs drive the plural data lines;
- and
- installing gate driver integrated circuits (ICs) on one side portion of the liquid crystal panel, wherein the gate driver ICs drive the plural gate lines.
A liquid crystal display device, comprising:
- a liquid crystal panel, comprising,
- a first substrate having deposited thereon a plurality of stripe-shaped color filters and a black matrix arranged around the stripe-shaped color filters, wherein each color filter has one of red, green, blue and white colors,
- second substrate disposed opposing the first substrate and having a plurality of gate lines arranged in a transverse direction, a plurality of data lines arranged in a longitudinal direction, and a plurality of sub-pixels each formed at an intersection of one of the gate lines and data lines, and
- a liquid crystal material deposited between the first and second substrates,
- wherein each sub-pixel corresponds to one of the stripe-shaped color filters;
- at least one gate driver integrated circuit (IC) connected to the gate lines for driving the gate lines, each gate driver IC disposed on a same side portion of the liquid crystal panel;
- and
- at least one data driver integrated circuit (IC) connected to the data lines for driving the data lines, each data driver IC arranged on a same one of a top side portion and a bottom side portion of the liquid crystal panel.
A method of driving a liquid crystal panel, including a first substrate having deposited thereon a plurality of stripe-shaped color filters and a black matrix arranged around the stripe-shaped color filters, wherein each color filter has one of red, green, blue and white colors, and including a second substrate disposed opposing the first substrate and having a plurality of gate lines arranged in a transverse direction, a plurality of data lines arranged in a longitudinal direction and a plurality of sub-pixels each formed at an intersection of one of the gate lines and data lines, and further including a liquid crystal material deposited between the first and second substrates, the method comprising:
- driving the data lines, each data line driving sub-pixels corresponding to a same one of the red, green, blue of white colors;
- driving the gate lines, alternating a polarity of a gate line driving signal for each of the gate lines at each frame interval.
