Abstract

The application discloses a circuit board and a display device, which include a plurality of pads arranged on the circuit board, and the pads at least include first pads and second pads that are adjacent and spaced apart; welding of the first pads A first solder resist is provided on the surface of the second pad, and a second solder resist is provided on the welding surface of the second pad; in the direction perpendicular to the welding surface of the first pad, the first solder resist separates the first pad into two Part, one part is the first spacer close to the second pad, and the other part is the first welding part away from the second pad; in the direction perpendicular to the welding surface of the second pad, the second solder resist The pad is divided into two parts, one part is a second spacer close to the first pad, and the other part is a second welding part away from the first pad. This application can save the material cost of the resistor and the manufacturing process cost of the patch, and further save the cost. The two layers of solder resists are separated, the requirements for the amount of solder material will be lower, the solder material will be saved, and the quality of the connection between the pads will be guaranteed.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a circuit board and a display device. Background technique [0002] An LCD (Liquid Crystal Display, liquid crystal display) includes a display unit for displaying images and a backlight unit for providing backlight for the display unit. The display unit includes a liquid crystal panel and a first PCB (Printed Circuit Board, printed circuit board) for driving the liquid crystal panel. The liquid crystal panel includes a first substrate on which pixel electrodes are formed, a second substrate on which common electrodes are formed, and a liquid crystal layer interposed between the first substrate and the second substrate. The backlight unit includes a light source module and a second PCB for driving the light source module. The LCD having the above structure generates an electric field between the pixel electrode and the common electrode, and adjusts the strength of the...
